2.4 Turning the Meter On

2.5 Temperature Measurement

Hach electrodes with the 5-pin connector have the temperature
sensing unit included in the electrode probe. If using an electrode
with BNC connector, connect a Hach Temperature Probe
(Cat. No. 51980) to the 5-pin connector on the meter (see
Figure 6). Or measure the temperature manually and enter the
value as the default temperature using the arrow keys.
After the batteries are installed, turn the instrument on using the
key (located on the upper left side of the keypad). Press
I/O/EXIT
the key once to power the instrument up. The display will show
the software version number, then move to the Reading mode.
The meter displays temperature in the range of -10.0 to 110 °C
simultaneously with sample results. If a temperature probe is
properly connected, actual temperature measurements are
displayed in the temperature/mV field.
The meter requires a temperature to calculate temperature-
corrected pH readings. The meter uses temperature data from one
of three sources:
•
The temperature sensor in the sample
•
The factory default setting (25 °C)
•
A user-entered setting (which becomes the default)
If a temperature probe is connected properly, the meter will
display the current sample temperature and will not allow the
temperature to be manually set.
To manually set the temperature
When a temperature probe is not used to supply the temperature
for pH temperature compensation, the temperature must be set
manually or the factory default temperature (25 °C) will be used.
In either case,
Default
To change the default temperature, first put the meter in Reading
or Calibration mode. Press the arrow keys to increase or decrease
