9-2-5 CAL (Balance calibration)
The internal balance of the MOC-120H may be calibrated at two points: at the 0 and 100grams. The
MOC-120H may also be connected to a printer to make it possible to automatically generate
calibration records in compliance with GLP, GMP, and ISO standards.
* The power to the unit should be turned on at least 30 minutes before calibration is performed in order to
ensure accurate calibration.
* The MOC-120H is extremely sensitive to interference from drafts, breezes, vibration, and other
disturbances in the surrounding environment, and care should be taken to ensure that there is no such
interference before performing calibration.
* It is impossible to calibrate the balance accurately immediately after performing measurements or at
any other time when the heater lid is hot. Allow the temperature of the heater lid to cool down to
ambient temperature before performing calibration.
* The weights used should consist of standard OIML weights or some other type of non-magnetic Class 1
weights. (The use of Class E2 or Class E1 weights is recommended.)
* When placing the weight on the sample pan, it should be placed in the center of it.
* The heater lid must be closed during calibration to prevent influence of drafts or air flow, and the height
of the weights used should be such that they do not come into contact with the temperature sensor or
heater.
* If you wish to abort a calibration already in progress, press the
TARE/RESET
key. An ‘Abort’ message will be
displayed and the display will return to the weight in grams.
Scale calibration procedure
Display Key(s) used Operating instructions
With the display of the weight in grams, press the

key until the ‘CAL’ menu item is displayed.
Press the
ENTER
key. This will cause the calibration settings to be
displayed and the setting ‘100.000’ to flash.
If you wish to change the value of the weight to be used, then
press the
SELECT
key. This will cause the displayed value to stop
flashing. Next, press the key or key to enter a value for
the weight. Pressing the
ENTER
key then causes the specified weight
value to flash.
Open the heater lid and place a calibration weight of the specified
weight value on sample pan. Closing the heater lid and pressing the
ENTER
key causes ‘- - - -’ to be displayed, 100-gram calibration to
come to an end, and then a flashing value of ‘0.000’ to be
displayed.
With the value ‘0.000’ flashing, open the heater lid and remove
the calibration weight.
Closing the heater lid and pressing the
ENTER
key causes ‘- - - -’ to
be displayed, 0-point calibration to come to an end, and then an
‘END’ message to be displayed.
* If the unit is connected to the optional printer, a calibration record
will be automatically printed out.
After a few seconds, the display will return to the regular weight
display.
