An accurate and robust electronic rising plate pasture meter for measuring pasture cover in grass paddocks that’s straightforward to use and simple to understand. The unique folding handle design and removable plate also make the Filip’s Electronic Folding Plate Meter EC-09 easy to transport, store and carry between paddocks.

The EC-09 Electronic Plate Counter automatically records each reading and displays values for number of samples taken, plus average pasture height and cover. Different pasture cover calculation formulas can be entered and selected, with the selected formula remaining in use until changed. All data and records are retained when the counter is switched off.

Jenquip Pasture Management Software and a comprehensive instruction handbook are included with each Filip’s Electronic Folding Plate Meter. The software is supplied on CD for use with Windows XP or later versions. Software for earlier Windows versions or on floppy discs can be supplied on request.

In addition, Carry Bags are available separately as Optional Extras.

Example pasture cover formulas for entering into the EC-09 Electronic Plate Counter can be found in the handbook or on the Feed Budget Cycle page.

Also available without the EC-09 Electronic Plate Counter as the Filip’s Manual Folding Plate Meter.

  • Electronic Plate Counter — automatically records readings and calculates pasture cover.

  • Accurate measurement — second only to cutting, drying and weighing pasture samples.

  • NEW! Integrated counter case — protects the potentiometer, less to go wrong, less maintenance required.

  • Folding handle — for easy transport and storage in supplied Carry Bag.

  • Measurement range — 0-250mm of compressed pasture height (0-400mm with optional Extended Shaft).

  • Pasture Management Software — makes feed budgeting quick, easy and accurate.

  • Hand-calibrated — ensures readings taken by all Filip’s Folding Plate Meters are comparable.

  • Repairable — without changing reading accuracy, allowing new results to be compared old.

  • Reliable — high quality materials and accurate manufacturing ensure reliability and long service life.

The Filip’s Folding Plate Meter is supplied in two parts:

  • The plate — lightweight aluminium disc that sits on top of the grass during measurement.

  • The folding handle — easily folded for carrying and transport, extended when the meter is in use.

To unfold, simply straightening the handle, then slide the hinge lock tube over the hinge assembly.

Screw the plate onto the threaded boss, ensuring the printed side of the plate is facing upwards and the meter is ready to use.

Folding is the reverse of the above process, with the sample counter left in position.

How to use the Filip’s Electronic Folding Plate Meter

Prior to measuring grass cover, enter or select the required pasture cover calculation formula (examples can be found on the Feed Budget Cycle page).

On entering a new paddock, zero the EC-09 Electronic Plate Counter. The Filip’s Folding Plate Meter is lowered vertically onto the grass, with the shaft dropping through to rest on the ground, leaving the plate supported by the grass.

The area and weight of the plate have been carefully calibrated for accuracy, and the taller and denser the grass, the further off the ground the plate rests. Grooves on the handle allow combined grass height and density to be measured in ½ centimetre intervals ( ‘clicks’).

The EC-09 Electronic Plate Counter will record the position of the plate relative to the ground in centimetres, instantly displaying the result in terms of grass height and calculated pasture cover.

Walk across the paddock, taking typically 30 to 50 sample readings. At the end of the paddock the EC-09 Electronic Plate Counter will display average height and pasture cover values which should be noted before moving on to the next paddock. It can also display the number of samples taken and average height.

Zero the EC-09 Electronic Plate Counter and repeat the process for each paddock being measured.

Example pasture cover equations for entering into the EC-09 Electronic Plate Counter can be found in the handbook or on the Feed Budget Cycle page. The pasture cover figures can be entered into the supplied Jenquip Pasture Management Software to calculate available pasture dry matter.

Rising plate pasture meters have been developed over a number of years to be simple, effective yet reliable. They are second only to cutting drying and weighing pasture for accuracy as they allow accurately for various pasture densities. However to retain this accuracy and ensure many years of trouble free use a little maintenance is recommended.

Before Use

When fitting or removing the plate it is easier if the counter is moved along the grooved rod a little.

After unfolding the meter and assembling the plate onto it, move the plate up and down a few times to ensure no binding occurs. If its movement is restricted (e.g. there are tight spots) the reason must be found and cured before the meter is used.

After Use

We have some sad examples returned to us for repair. The worst have been subject to chemicals — often fertiliser, maybe out of the paddock, water troughs or in the shed. If you suspect chemicals or other contaminants have got to the meter a good wash in fresh water and subsequent dry out is required.

Remove the plate and wash it clean. Mud or extra weight on the plate is undesirable.

Wash / wipe and dry the area around the bottom of the meter. Move the counter fully up so that all dirt and accumulated grass can be wiped or washed away especially around the lower part of the grooving on the shaft.

Occasionally, maybe every second month, move the counter up and apply light oil (CRC, WD40 or similar) to the grooved rod. Wipe all excess oil off.

Apply some dry lubricant or light oil to the hinge assembly and to the inside of the hinge lock tube. Store the meter in its folded position.

These are precision meters — look after them.

The other important thing is the operator’s manual — it contains a wealth of information on all aspects of feed budgeting and the use of a rising plate pasture meter, including the various formulas or equations that can be used. At Jenquip, we often get calls from operators wanting to know about the formulas — it’s all in the operator’s manual.

Contact us if you need a replacement operator’s manual sent, or download a copy from the ‘Service & parts’ tab. Take care to order / download the correct operator’s manual for the model of plate meter you are using.

If in doubt, it is worth Zero Calibrating the meter just to make sure it is correct. Refer to specific model handbook
for Zero Calibration instruction, around page 7 or in the section that includes selecting and changing formulas.

Please check the following before contacting Jenquip.

High results

Check your technique to ensure you are not ‘rolling’ the meter. The meter should always be placed on the ground at 90 degrees to it. This can easily be achieved while walking especially if it has a ball knob as a handle.

Low results

Electronic counter cog not counting correctly:
Check Resolution

Cog not aligned correctly on the shaft.

Re-align the cog.

Cog worn.

Replace the cog with a new part ordered from Jenquip.

Meter plate not running freely:
Check Resolution

Alloy shaft is bent.

Straighten, or order a replacement part from Jenquip.

Grass or soil build-up inside the black tube.

Clean the Plate Meter.

Grooves on alloy shaft have become filled with grass or soil.

Clean the Plate Meter.

Specific notes for Electronic Plate Meters

Electronic meter needs recalibrating:

Note: 99% of problems are due to the electronic counter being out of calibration.

If in doubt, it is worth Zero Calibrating the meter just to make sure it is correct. Refer to specific model handbook for Zero Calibration instruction, in the section that includes selecting and changing formulas.

Before recalibrating, check for any potential physical problems listed in the table below which may have caused the meter to need recalibrating.

There is no visual display:
Check Resolution

The counter is not turned on.

Turn on.

The battery is flat.

Replace battery.

If you have just changed a battery you may have damaged the battery snap (clip to top of the battery).

Service – send to Jenquip.

The counter continuously beeps and eventually turns off:
Check Resolution

This is normally due to a low battery. The counter requires a given level of power to operate correctly. If the battery doesn't have sufficient power it may continuously beep to warn you. Remember if you turn the counter off for a few minutes it may recover slightly but the problem will not go away.

Recharge the battery.

Battery may be due for replacement.

Requires electronic service.

The counter does not "beep" when taking a reading:

If the counter does not beep, it means that the counter does not know where the bottom is — therefore does not record the ‘plonk’. Zero calibrate the meter. Refer to specific model handbook for zero calibration instruction.

Check Resolution

The cog has wound off.

Replace – order a replacement cog from Jenquip.

Potentiometer damaged (the potentiometer is the shaft part that drives the cog).

Send to Jenquip for service and repair.

Note:Under no circumstances should you apply CRC or a light oil to the potentiometer. It is a dry bearing and any lubricant will render the potentiometer useless.

Check the alloy shaft is coming right back into the base of the black tube.

Clean the Plate Meter.

Ensure there is no grass or soil build-up preventing the Plate from moving freely.

Check the washer at the bottom of the shaft is not catching on the bottom of the plate.

Check the cog is running smoothly on the shaft.

Re-assemble the Plate Meter.

If the counter is mounted too close to the alloy shaft there will be quite a lot of friction when taking a reading.

If the counter is mounted too far away from the alloy shaft, the cog is liable to jump a notch easily.

Front Panel (membrane) problems:
Check Resolution

Buttons not clicking or activating.

Service - membrane needs replacing.

Send to Jenquip for service and repair.

Battery Retainer keeps falling out:
Check Resolution

The counter screws have not been tightened sufficiently.

Ensure the battery retainer is properly clicked into place and make sure the centre screw is re-tightened after the battery is replaced.

Counter Readings do not seem accurate:
Check Resolution

The counter is like a calculator - it does not give false readings under normal circumstances.

Check the equation being used is correct and the calibration has been correctly set (zeroed).

Note: In New Zealand there are a number of standard equations published by various organisations. These reflect regional pasture types. If you wish to change an equation or select alternative species you will need to contact your consultant.

Traditionally the equation of pasture height x 158 plus 200 was used. However, there has been a series of equations produced to reflect changes in pasture types and physiological state (vegetative, flowering, seed head) which can alter DM levels in the paddock.

A more accurate calibration can be achieved by taking cuttings or your consultant may be able to advise you on the most appropriate equation for your situation. This particularly applies to pastures under irrigation.
