Continuity Measurement; How To Use 25W Calibration Checker - AEMC 3620 User Manual

4.6 Continuity
Measurement
Connect the shorting strip between
Y (P2) and Z (C2).
Continuity measurement is made
with two leads, one from X, the
other from Y– Z (P2, C2); push the
"Press To Measure" button to mea-
sure.

How to Use 25W Calibration Checker

The calibration checker has a resistance of 25W. The procedure to use the
calibration checker is as follows:
• Loosen the X, Y and Z terminals.
• Insert the resistor as shown in Figure 11.
• Tighten down the terminals X, Y and Z.
• Push down the Press to Measure button.
• Compare the reading on the display to the measurement range
provided on the label.
NOTE: For alignment purposes of the test resistor it is best if the shorting link
is connected between Y and Z.
