ST2516 Series Operation Manual

5.3

Measurement Accuracy

Checking the measurement accuracy should be taken under the following circumstances:

．

Warm-up time should be more than 30 minutes.

．

Correctly short the test cables, turn 0 ADJ to ON and perform short calibration
by pressing the touch key or 0 ADJ panel.

The correct short of the test cable is as follows:
