Data Hold
Data Hold is not available when “OL K
Ω
”
displayed with no input signals.
Data Hold Beep Guard
The internal sounder will operate
continuously with LCD display flashing in
two situations in the Data Hold mode:
1. The Meter measure a signal different
from the LCD reading.
2. The measured signal is the same unit
as the LCD reading and is larger 50
counts than the LCD reading.

AC Conversion Type :
AC Conversions are ac-acoupled, true
RMS responding, calibrated to the RMS
value of a sine wave input. Accuracies
are given for sine wave at full scale and
non-sine wave below half scale. For non
-sine wave add the following Crest
Factor corrections :
For Crest Factor of 1.4 to 2.0, add 1.0%
to accuracy.
For Crest Factor of 2.0 to 2.5, add 2.5%
to accuracy.
For Crest Factor of 2.5 to 3.0, add 4.0%
to accuracy.
