Measurement and Display Considerations

•
If the unit appears to be locked (display frozen). It is possible that the Data Hold mode
has been inadvertently accessed by pressing the MODE button. Simply press the
MODE button again or turn the meter off and restart if the display appears frozen.
•
If the meter does latch up and no button presses revive it, remove the batteries and
restart.
•
Note that if the batteries are removed, any stored readings will be discarded. Also, the
calibration for pH will be cleared requiring recalibration. Calibration data for ORP or
Chlorine will be retained however.
