5. Calibration procedures

Warning
●
Before using the new instrument or after exchanging the strain gage
applied transducer with a new one, be sure to make calibration.
If calibration is not made, correct measured results may not be
obtained, or it may cause malfunction to the instrument and it may
damage the peripheral equipment.
Moreover, even if calibration has made, there may occur the similar
case as above when the result is not correct. So, make precise
calibration again.
●
Make calibration with shorted between A/Z OFF and A/Z COM when
optional Auto zero function(CSA − 507C − 99) is attached.
5 − 1. Preparation
According to the section 4. Connecting method, connect the instrument and strain gage applied
transducer properly and then supply the power.
5 − 2. Calibration method
There are following 2 kinds of load calibration procedures for the instrument.
1
Calibration with actual load
2
Electrical calibration by the CALIB input.

is 1/500 or so.
In the following paragraphs, we will describe each calibration procedure by showing the examples
with load cell applied.
