• Press CFM to confirm the selected parameter that will stop
blinking on the primary display. The secondary display shows
the HI 931002 or multimeter input value as lower limit of
the interval.
• Use the or to make the
HI 931002 or multimeter out-
put correspond with the
meter’s value shown on the
secondary display (e.g. 4).
• Wait for approximately 30 seconds (until the reading of
the calibrator is stable).
• Press CFM to enter. The meter will switch to the second
calibration point. Repeat the above procedure.
• After the desired readings are obtained, press CFM and
the meter will skip back to normal operating mode.
Note When adjusting values using the or it is important to
allow for sufficient response time (up to 30 seconds)
The table below lists the values of output codes along with
the calibration point values (which are the analog output
minimum and the analog output maximum) as indicated
on the display.
The secondary display indicates the current calibration point
value, while primary display indicates the current calibra-
tion type.
• Immerse the temperature probe in
the second beaker as near to the
Checktemp as possible and repeat
the above procedure.
Calibration procedure may be interrupted by pressing CAL
again at any time. If the calibration procedure is stopped
this way, or if the controller is switched off before the last
step, no calibration data is stored in non-volatile memory
(EEPROM).
ANALOG OUTPUT CALIBRATION
In the meters where the analog output is available, this
feature is factory calibrated through software. The user may
also perform these calibration procedures.
IMPORTANT It is recommended to perform the output calibration at least
once a year. Calibration should only be performed after
10 minutes from power up.
• With a multimeter or an HI 931002
connect the common port to the
ground output and the second port
to the current output or voltage out-
put (depending on which parameter
is being calibrated).
• Press and hold in sequence CFM first, then and then
CAL to enter the Analog Output Calibration mode.
• Execute the password procedure.
• The primary display will show the current selected param-
eter blinking. Use the to select the code (0-5 see chart
below) for the desired parameter displayed on the second-
ary display (e.g. 4-20 mA).
