POWER CONNECTION
Plug the 12 Vdc adapter into the power supply socket.
Note:
These instruments use non-volatile memory to retain the meter settings, even when unplugged.
ELECTRODE AND PROBE CONNECTIONS
For pH or ORP measurements, connect a pH/ORP electrode with internal reference to the BNC connector
located on the rear panel of the instrument.
For ISE measurements (
HI 5522
), connect an ISE electrode with internal reference to the BNC connector
located on the rear panel of the instrument.
For electrodes with a separate reference, connect the electrode’s BNC to the BNC connector and the
electrode’s reference to the reference input socket.
For temperature measurement and automatic temperature compensation, connect the temperature probe to
the appropriate socket (Channel 1 only).
For conductivity, resistivity, TDS or salinity measurements, connect a conductivity probe to the DIN connector
located on the rear panel of the instrument.
