7.9 Conductance
Range | Resolution | _ Input protection Description
Whien the measured resistance is less than
300, the buzzer sounds; when the reading is
0-20 00010 250Vp less than 2KQ, "-OL-" is displayed when it
exceeds. The threshold resistance can be set
in the range of 0 to 2kO.

8 Calibration
Note:
1) Betore calibration, it is required to prcheat the instrument for more than 30 minutes. The
accuracy of the standard source must be better than 3 — 5 times the accuracy of the calibrated
instrument.
2) After a specific range was calibrated, the calibration data i
you can just calibrate a separate range
3) In order to prevent inaccurate calibration due to wrong operation, it is required to enter a
password before the calibration.
4) You can enter the calibration interface after input the correct password. Take the interface of
DCV calibration as an example
mediately written to FLASH. So
