5.2.3 Deadloading the Scale (scale zero)
Before the indicator can be calibrated the deadload or scale zero value must
be obtained. Remove all test weights from the scale. Key parameter 12
followed by the PRINT/SELECT key. The display will show ‘r’ for
“reconfirm”. Press 1 followed by the TARE key to confirm to continue with
deadloading the scale. The indicator will pause for a short duration and then
display the deadload value in AD counts to the display. The indicator will
then return back to weight display mode. The indicator can now be
calibrated with a known test weight.
5.2.4 Spanning the indicator
Place a known test weight on the scale. Enter 13 followed by the
PRINT/SELECT key. The display will briefly flash “1”. Shortly after the
display will freeze with the last displayed weight. Enter the value of your test
weight followed by the TARE key. The indicator will immediately calibrate
and return back to weight display mode. If the display shows “EEEEEE”
then you have exceeded the scale capacity value set in parameter 4 and 8. If
the display shows “AAAAAA” then you have exceeded the input analog
range of the indicator. The output voltage from the load cells exceeds the
input for the AD converter.
Once the proper weight is displayed, exit calibration mode by pressing 99
followed by the PRINT/SELECT key.
5.3 Sealing the indicator
The M2000 is sealed electronically with a password. There is also provision
for physical sealing on all products. The 42300 and 42300M have faceplate
screws that accommodate a wire and lead seal.
5.3.1 Electronic Seal
Passwords are 4 digit numbers. The factory default for the password is 1111,
which can be changed in calibration mode. To change or view the password
in calibration mode use parameter 96. Enter a 4 digit password followed by
the TARE key. Important note: if you forget your password you will not be
able to enter calibration mode on the indicator. Contact the factory for
assistance at 604-941-3474.
5.3.2 Audit Trail
The M2000 is equipped with a Category 1 Audit Trail system. It is
important that the correct time and date be set, as this is saved as part of the
