3. Calibration
3-1. Calibration method
The load calibration method of this instrument has two kinds of the following.
① Calibration with actual load
② Electrical calibration by the CALIB input
Caution
● 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, the correct measurement 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.
● When the auto zero option (CSA-522B-99) is applied, please calibrate with pushing the A/Z OFF switch, or shorten between A/Z OFF and
A/Z COM for about 100 ms or more.
● Please make the calibraton while the CALIB switch turns off.
● The accuracy of calibration by CALIB input is 1/500 or so.
