Crest Factor Check
This test verifies the voltmeter's crest factor performance. The signal
measured for this test is a dc voltage taken at the rear-panel dc output
jack. This voltage is normalized to -Q.9487 Vdc and is proportional to
the RMS input voltage (-Q.9487 Vdc corresponds to a full·scale meter
deflection).
