POWER CONNECTION
Plug the 12 Vdc adapter into the power supply socket.
Note: This instrument use non volatile memory to retain the meter settings, even when
unplugged.
ELECTRODE AND PROBE CONNECTIONS
For conductivity, resistivity, TDS or salinity measurements connect a conductivity probe to the DIN
connector located on the rear panel of the instrument.
INSTRUMENT START UP
• Please ensure that the capacitive keypad is not covered by hand or other objects at the meter
power on.
• Turn the instrument on from the power button located on the rear panel of the instrument.
• Please wait until the instrument finishes the initialization process.
Note: It is normal for the loading process to take a few seconds. If the instrument doesn’t
display the next screen, restart the meter using the power switch. If the problem persists,
contact your dealer.
