• Press CFM to confirm the parameter that stops blinking on
the primary display.The secondary display shows the multi-
meter or HI931002 input value as the interval lower limit.
• Use
or
to make the
HI931002 or multimeter output
correspond with the value shown
on the secondary display (e.g. 4).
• Wait until the calibrator reading is stable (approx. 30 sec.).
• 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 values (which are the analog output mini-
mum and maximum) as indicated on the display.
The secondary display indicates the current calibration value,
while primary display indicates the current calibration 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 fea-
ture 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 or voltage output (depend-
ing 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 next
chart) for the desired parameter displayed on the second-
ary display (e.g. 4-20 mA).
