MEASUREMENT PROCEDURES
Preparing for Measurement
1. Assemble the probe holder and attach the holder to the meter
(pages 6-7).
2. Connect an adaptor to the power jack. Slide the adaptor jack into the
meter, making sure it is firmly in place. (The meter’s voltage is 9V.)
3. For pH and ORP measurements, connect a sensor probe to the BNC
port. For conductivity, TDS and salinity measurements, connect a
sensor probe to the MIC port.
4. For a pH probe with a temperature sensor, connect a temperature
sensor connector to the ATC port.
5. Connect a USB or RS232 cable to the meter and your computer
to upload real time measurement values and memories for further
analysis (page 44).
6. Connect your chart recorder or other data collection devices to the
ANALOG port as needed.
Available measurement parameters for each probe type:
pH
mV/ORP
Cond. TDS Salinity
pH Probe
Cond. Probe
ORP Probe
IMPORTANT:
The temperature of the measured liquid must be stable.
pH and conductivity probes CANNOT be placed in the same container
while taking measurements.
