If your TPS Measuring Instruments displays the word 'OFF' and then switches off, it means the battery voltage has dropped below 6.00 volts. To fix this, replace the battery.
What to do if my TPS Measuring Instruments will not turn on?
If your TPS Measuring Instruments won't turn on, the battery is likely exhausted. Replacing the battery should solve the problem.
What does the flashing symbol mean on my TPS Measuring Instruments?
If your TPS Measuring Instruments shows a flashing symbol, it indicates that the battery is below 7.50 volts. Replace the battery soon. The unit will automatically switch off when the battery level falls below 6.00 volts.
Why are the readings inaccurate on my TPS Measuring Instruments even after calibration?
If your TPS Measuring Instruments shows inaccurate readings even after successful calibration, the reference junction is likely blocked. Clean the reference junction according to the instructions supplied with the sensor to resolve this.
Why does the 2 point calibration fail on my TPS Measuring Instruments (slope less than 85.0%)?
If a 2-point calibration fails on your TPS Measuring Instruments because the slope is less than 85.0%, it could be due to several reasons: 1. Using an incorrect primary buffer. 2. The glass bulb is not clean. 3. The sensor is aged. 4. The connector is damp. 5. The buffers are inaccurate. To solve this: * Ensure you are using the buffers that the Aqua-pH has been set to automatically recognize. * Clean the glass bulb as per the instructions supplied with the sensor. * Attempt rejuvenation as per the instructions supplied with the sensor. Replace the sensor if rejuvenation is unsuccessful. * Dry the connector in a warm place. * Replace the buffers.
Why does the 1 point calibration fail on my TPS Measuring Instruments (asymmetry greater than +/- 1.00 pH)?
If a 1 Point calibration fails on your TPS Measuring Instruments (Asymmetry is greater than +/- 1.00 pH), it is likely due to a blocked reference junction or contaminated reference electrolyte. Clean the reference junction as per the instructions supplied with the sensor, flush with distilled water, and replace the electrolyte.
Why does my TPS Measuring Instruments display 7.00 for all solutions?
If your TPS Measuring Instruments displays 7.00 for all solutions, there is likely an electrical short in the connector. Check the connector and replace it if necessary. If the problem persists, replace the sensor.
Why does my TPS Measuring Instruments display 4-5 pH for all solutions?
If your TPS Measuring Instruments displays 4-5 pH for all solutions, the glass bulb or internal stem is likely cracked. The solution is to replace the sensor.
What to do if my TPS Measuring Instruments fails to calibrate, even with a new sensor?
If your TPS Measuring Instruments fails to calibrate, even with a new sensor, the calibration settings are likely outside of allowable limits due to a previous failed calibration. Initialise the unit.
Why does my TPS Measuring Instruments display “OVRoC” when the sensor is plugged in?
If your TPS Measuring Instruments displays “OVRoC” when the sensor is plugged in, it indicates either a faulty sensor or a faulty instrument. Try fitting a new sensor, part number 121247. If the issue persists, return the instrument to the factory for repair.
