GENERAL OPERA
TIONS
7.2. CONNECTING THE PROBE
To prepare the instrument for field measurements close the serial communication socket and all unused
connector sockets with proper stopper (to ensure waterproof protection). Use the holed temperature
rubber cork for the temperature socket when temperature probe is connected.
Connect the pH electrode and the temperature probe to the BNC and temperature sockets on the top of
the instrument. Push the pH electrode sleeve to cover the connector accommodation.
The temperature probe is used in conjunction with the pH electrode to utilize the instrument’s ATC
capability, but it can also be used independently to take temperature measurements. If the probe is
disconnected, temperature can be set manually with the / keys.

percentage indication of the remaining battery life, then enters the measurement mode.
7.4. BACKLIGHT FEATURE
The instrument is provided with a Backlight feature. Press

to switch the backlight on/off.

The backlight automatically shuts off after a set period (see METER SETUP section for
