• 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 a
few minutes from power up.
• With a multimeter or an
HI931002 connect the common
port to the ground output and
the second port to the current
or voltage output (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 pa-
rameter blinking. Use the
to select the code (0-5 see
next chart) for the desired parameter displayed on the
secondary display (e.g. 4-20 mA).
