the displayed default temperature value to the desired
temperature. The value adjusts in 0.1 °C (0.1 to 0.2 °F)
increments.
Note: Acceptable temperatures range from -10 to 110 °C.
To change the units of temperature measurement, see
Section 3.1.3 on page 26.
2.6 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.
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.
2.7 Automatic Shut-off Function
The meter is equipped with an automatic shut-off feature to
prolong battery life. The meter will automatically shut off
15 minutes after the last key press unless the meter is in
Calibration mode. If it is in Calibration mode, automatic shutoff
will occur four hours after the last key press.
Press the I/O/EXIT key after automatic shut-off to restore power to
the instrument.
