How to fix temperature if it is inaccurate and cannot be calibrated on TPS WP-80 Measuring Instruments?
If the temperature reading is inaccurate and cannot be calibrated, there may be a faulty connector or temperature sensor. Check the connector and replace if necessary. If the problem persists, fit a new temperature sensor, part number 121247.
What to do if my TPS WP-80 unit fails to calibrate, even with a new sensor?
If the unit fails to calibrate even with a new sensor, the calibration settings may be outside allowable limits due to a previous failed calibration. Initialise the unit.
Why does my TPS WP-80 display “Man” when the temperature sensor is plugged in?
If the display shows 'Man' when the temperature sensor is plugged in, it could indicate a faulty temperature sensor. Try fitting a new temperature sensor, part number 121247.
What does it mean if my TPS WP-80 Measuring Instruments display flashes “ATC” and “LIMIT”?
If the display flashes “ATC” and “LIMIT”, the temperature is not within the ATC limits. Cool or heat the solution before taking measurements.
Why are my TPS WP-80 readings inaccurate, even after calibration?
Inaccurate readings after calibration may be due to a blocked reference junction. Clean the reference junction as per the instructions supplied with the sensor.
What to do if my TPS WP-80 meter displays the word OFF, and switches off?
If your meter displays 'OFF' and switches off, the battery is likely below 5.00 volts. Recharge the battery. If this doesn't work, check the charger and replace the battery if the charger is OK.
What to do if my TPS WP-80 battery does not charge?
If the battery isn't charging, it could be a faulty charger or battery. Connect the charger and switch the power on. Display the battery volts in the battery saver menu. If the battery volts are increasing, the charger is OK. If the battery volts do not increase, then the charger is faulty. Replace the charger or the battery, as required.
