on by rotating the selector to VAC (v). Combo or
Meter display mode should appear, with a
random display in the mV range.
2. Rotate the selector to VDC (E) Observe a similar
primary display in the mV range.
3. Rotate the selector to Ohms (R). Observe a
display of “OL”.
4. Connect the test leads to V and C.
5. Short the test lead tips and observe a display of
approximately 0.250 ohms.
1. A test pattern.
2. An error message (if a problem is encountered
during the test). The GMM test tool Model and
serial numbers.
3. The calibration status.
