To manually set the temperature
When temperature probe is not in use, put the instrument in
Reading or Calibration mode and enter the default temperature by
using the arrow
keys to change the default temperature value on
the display to the desired temperature. The value adjusts in 0.1 °C
(0.1 to 0.2 °F) increments. Hold the arrow key down to rapidly
scroll the temperature value. The factory default is 20 °C.
Note: Acceptable temperatures range from -10 to 110 °C.
To change the units of temperature measurement, see Section
3.1.3 on page 24.
2.7 Millivolt Measurements
The meter can be used to measure absolute millivolts (mV). To
display a current millivolt reading, press the
pH/mV
key. The mV
value is displayed with
mV
in the units field. Press the key again
to return to pH measurement units.
Absolute millivolts are displayed with 0.1 mV resolution in the
range of -2000 to +2000. The millivolt mode is useful when
measuring oxidation-reduction potential, performing
potentiometric titrations, or preparing calibration curves. Detailed
instructions for any Hach electrode are given in the electrode
instruction manual. Titration instructions are included in the Hach
ORP Electrode Instruction Manual, or in standard analytical
chemistry texts.
