2. GETTING STARTED
2.1 Keypad Functions
Powers the meter on and off. Upon power on, the meter
automatically begins in the mode that was last used.
Calibration and memory values are retained even if meter
is unplugged.
Toggle between available measurement modes—
pH/Temp, mV/Temp, Conductivity/Temp, or TDS/Temp.
Also used to switch to Temperature calibration during pH,
mV, Conductivity or TDS calibration modes.
Press and hold for 5 seconds to enter SETUP mode.
Toggles between measurement and calibration modes.
In SETUP mode, returns user to the measurement mode.
Confirms calibration values in CAL mode.
Confirms selections in SETUP mode.
Changes Con/TDS range and resolution in MEAS mode.
View recalled values in memory mode.
MI (Memory Insert) stores values into memory.
Increase value. Scroll up in SETUP & CAL modes.
MR (Memory Recall) recalls values from memory
Decrease value. Scroll down in SETUP & CAL modes.
Freezes measured reading. Press again to resume
live reading.
