Zero calibration
1.
Start zero calibration.
Check that a sensor is in an unloaded condition,
and press the
→
keys.
As soon as an indicated value becomes zero, zero
calibration is complete.
4-9.
Actual load calibration
1.
Start actual load calibration.
→
2.
Apply actual load to a sensor
and set the value of the actual load.
Check that the actual load is being applied to a sensor
using the
(numerical value input) and
(shift) keys, and confirm it with the
key.
As soon as an indicated value becomes the actual load
value, actual load calibration is complete.

In case a calibration error is displayed, perform countermeasures according to
each error and re-perform the calibration.
....... The output of a strain gauge type sensor does not reach
the span adjustment range (approx. 0.05mV/V).
Check that actual load is being applied to the strain gauge
type sensor. Calibration cannot be implemented in an
unloaded condition.
....... The strain gauge type sensor output falls below zero.
Check that + SIG and - SIG wires of a strain gauge type
sensor are not reversely connected.
As soon as calibration is complete, make sure to switch calibration LOCK ON.
