To Next PageTo Next PageWhat to do if my TPS WP-81 meter will not turn on?
If your TPS Measuring Instruments meter won't turn on, first, recharge the battery. If it still fails to turn on, check the charger. If the charger is working, replace the battery.
Why is there a flashing symbol on my TPS Measuring Instruments?
The flashing symbol on your TPS Measuring Instruments indicates that the battery is below 5.60 volts. Recharge the battery to resolve this. The unit will automatically switch off when the battery level falls below 5.00 volts.
What to do if my TPS Measuring Instruments displays 'OFF' and switches off?
If your TPS Measuring Instruments displays 'OFF' and switches off, it means the battery is below 5.00 volts. Recharge the battery. If the issue persists, check the charger. If the charger is working correctly, replace the battery.
What to do if my TPS WP-81 Measuring Instruments displays 'Memory Failed Calibration Lost Initialised MUST ReCalibrate'?
If your TPS Measuring Instruments displays 'Memory Failed Calibration Lost Initialised MUST ReCalibrate', user calibration settings have been lost or corrupted. Re-calibrate the instrument. A 2-point calibration will be required for Conductivity, & pH and a 1 point calibration for temperature.
What to do if my TPS WP-81 shows 'Factory Cal. Failed See Handbook'?
If your TPS Measuring Instruments displays 'Factory Cal. Failed See Handbook', it indicates that the EEPROM chip, which contains the factory calibration information, has failed. The unit must be returned to TPS for service.
