Key Function
ON/OFF Powers on and shuts off the meter. When you switch on the meter, the meter starts up
in the mode that you last switched off from. For example, if you shut the meter off in
conductivity measurement mode, the meter will be in conductivity measurement mode
when you switch the meter on.
HOLD Freezes the measured reading. To activate, press HOLD while in measurement mode.
To release, press HOLD again.
MODE Selects the measurement parameter. Press MODE to toggle between pH or TDS or
conductivity measurement mode.
CAL/MEAS Toggles between Calibration and Measurement mode.
1. If you are in pH measurement mode, press CAL/MEAS to enter pH calibration
mode.
2. If you are in conductivity measurement mode, press CAL/MEAS to enter
conductivity calibration mode.
3. If you are in TDS measurement mode, press CAL/MEAS to enter TDS
measurement calibration mode.
While in SETUP sub-menu, pressing CAL/MEAS once takes you out to the SETUP
main menu and pressing CAL/MEAS second time takes you directly into the
