• Press CFM to confirm. The meter will return to normal op-
erational mode.
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 nonvolatile memory (EE-
PROM).
ANALOG OUTPUT CALIBRATION
In the models where the analog output is available, this fea-
ture is factory calibrated through software. The user may also
perform these calibration procedures.
Note
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 output
(depending on which parameter is be-
ing calibrated).
• Press and hold in sequence CFM first, then ð and then
CAL to enter the Analog Output Calibration mode.
• Execute the password procedure.
• The primary display will show the selected parameter blink-
ing. Use the ñ to select the code (0-5 see chart below) for
the desired parameter displayed on the secondary display
(e.g. 4-20 mA).
