Why does my Hanna Test Equipment meter keep shutting off?
If your Hanna Test Equipment meter shuts off, it's likely due to dead batteries or the auto-off feature, which activates after 20 minutes of inactivity. Replace the batteries, or press the ON/OFF button to restart the device.
What to do if the display shows blinking battery symbol on Hanna HI 9124 Test Equipment?
If the battery symbol is blinking on your Hanna Test Equipment, it means the battery level is low. Replace the batteries to resolve this.
Why does my Hanna HI 9124 Test Equipment fail to calibrate or give faulty readings?
If your Hanna Test Equipment fails to calibrate or provides inaccurate readings, the pH electrode may be broken. Try replacing the electrode.
Why is the reading fluctuating on my Hanna HI 9124 Test Equipment?
If the reading on your Hanna Test Equipment fluctuates up and down, it could be due to a clogged or dirty junction, or a low electrolyte level (for refillable electrodes). Try cleaning the electrode, refilling it with fresh electrolyte if applicable, and checking the cable and connector.
What to do if Hanna HI 9124 Test Equipment shows 'WRONG CALIBRATION'?
If your Hanna Test Equipment displays "WRONG CALIBRATION" during pH calibration, the buffer solution may be incorrect or contaminated. Ensure that the buffer solution is correct and fresh.
How to fix slow response on Hanna HI 9124 Test Equipment?
If your Hanna Test Equipment shows a slow response or excessive drift, the electrode may be dirty. Clean the electrode following the cleaning procedure.
What to do if Hanna HI 9124 Test Equipment display shows blinking full scale value?
If the display on your Hanna Test Equipment shows a blinking full-scale value, the reading is likely out of range. Verify that the electrode is properly connected, the sample is within the measurable range, and the electrode is in contact with the solution.
Why Hanna HI 9124 Test Equipment does not work with temperature probe?
If your Hanna Test Equipment meter isn't working with the temperature probe, the probe might be broken or incorrect. Replace the temperature probe.
Why is my Hanna HI 9124 Test Equipment displaying a blinking temperature reading?
If your Hanna Test Equipment displays a blinking "°C" or "°F," the temperature probe is likely broken. Replace the temperature probe.
What does 'C lr' message mean on Hanna Test Equipment?
If your Hanna Test Equipment displays a "C lr" message at startup, it means default pH calibration values have been loaded. Perform pH calibration.
