Calibration
The following procedure describes how to Zero Calibrate and Span
calibrate the balance. These two are always done together.
Calibration
1. Turn scale off and remove the platter.
2. Locate the
CAL Switch
(rear of platform).
3. Press and hold down the
CAL Switch
while you turn on the scale.
4. Once the display reads
SPAn
, release the
CAL Switch.
5. Replace the platter on the platform.
6. Press the
¿
key.
7. After the STABLE lamp turns on, press the
¿
key.
8. The scale will display
rEAd
and then show
FULL
.
9. Press the
¿
key.
10. Once the STABLE lamp turns on, place the mass weight on the
platter.
This mass must be equal to exactly the balance’s
capacity in grams.
11. After the STABLE lamp turns on, press the
¿
key.
12. The scale will display
rEAd
, then show
End
, and then show
SELF
.
†
13. Remove mass weight from the platter.
14. Turn scale off and then back on.
†
NOTE:
The balance may show
HHHHHH
or
LLLLLL
at this point
instead of
End
.
If it displays
HHHHHH
then the mass weight that you are using to
calibrate is too heavy or the scale may need servicing (the load cell
may have been overloaded or shock loaded.)
If it displays
LLLLLL
then the mass weight that you are using to
calibrate is too light or the scale may need servicing (the scale may
have been dropped or mistreated.)
