Keep the meter in its protective case. Clean and dry the probe after every
reading. The point of the Bale Moisture and Bale Temperature Probes is very
sharp and should be handled with due care. Keep covered when not in use.
When removing the probe from the bale, avoid twisting the handle.

when the battery is empty. To change the battery, remove the screw in the
battery lid on the back of the meter. Slide the lid downwards to open the battery
compartment. Remove the battery if the instrument is not used for long periods.
Calibration Check
The meter calibration can be checked by the user with the Protimeter Calcheck
Device (Part No. BLD5086) and a 2
-
pin moisture probe (Part No. BLD5079),
connected via the bale probe socket on the side of the meter. If correctly
calibrated, the meter will display a value in the range 14.0 to 14.4 at 20°C.
Regular Servicing and Checks
According to most crop quality assurance schemes, your bale moisture meter
and probe should be checked annually against reference values. The Martin
Lishman service centre is fully equipped to service your meter throughout its
working life. We also conduct testing clinics where you can check your meter
and obtain a test certificate to satisfy your crop assurance scheme. See our
website for the latest clinic details and to download a service return form.
