- Then turn the microbalance off and back on again using the
key.
- While all segments are displayed (full-segment test), briefly
press the key.
- >> C.C.<< or >> C.L.<< now appears above the weight readout.
- Press the key until >> C.C. << is displayed.
- Press to tare the microbalance first, then press to
activate the calibration routine.
The internal calibration weights are now loaded and removed in
sequence by the servomotor. In the process, the weight stored
in the EEPROM of the microbalance is overwritten by the weight
currently displayed. Afterwards, the microbalance returns to the
standard weighing mode.
- At the end of the calibration routine, reset the menu code to
>> 1-10-2 << and lock the menu access switch.
Internal Calibration:
- Make sure that the menu code >> 1-10-1 <<
- internal calibration accessible - has been set on the
microbalance.
- As soon as the readout has stabilized, press the key.
- Confirm by pressing the key, and >> C.I. << will be
displayed.
- The internal calibration weights are now loaded and unloaded in
sequence by the servomotor. In the process, the weight value is
stored in the EEPROM of the microbalance processor.
Afterwards, the microbalance returns to the standard weighing
mode.
- At the end of the internal calibration routine, reset the menu
code to >> 1-10-2 << and lock the menu access switch.
Internal Self-Calibrating Function:
- To activate the internal self-calibrating function (ISOcal), check
that menu code >> 1-15-3 << has been set.
- When the microbalance wants to self-calibrate, a balance
symbol will flash on the display, and the microbalance will then
perform automatic internal calibration.
- If a printer is connected to the microbalance, a record of this
process will be printed on hard copy (for GLP/GMP compliance),
depending on the menu code setting (see page 2-31 in the MC5
instruction manual).
