AC Zero Input Behavior of True-rms
Meters
Average responding meters can accurately measure only
pure sinewaves. A True-rms meter can accurately
measure distorted waveform signals. A minimum input
voltage is necessary for calculating True-rms converters
to make a measurement. Because of this minimum input,
True-rms meter specifications are only good for 1 % to
100 % of range. Non-zero digits that are shown on a
True-rms meter when the test leads are open or are
shorted are possible. This has no effect on the ac
measurement accuracy of signals that are more than 1 %
of range.
Unspecified input levels on the lowest ranges are:
•
AC voltage less than 1 % of 600 mV ac or 6 mV ac.
•
AC current less than 5 % of 60 mA ac or 3 mA ac.
Wireless Radio Setup
The Product uses wireless radio technology to send or
receive measurements to other wireless test tools or the
Fluke Connect
®
app. The range of the radio is up to 20 m
(66 ft).
The term “discovery” in this manual refers to a procedure
the Product does to look for compatible radio signals. The
term “pair with” means the Product has made a wireless
connection to a test tool or the Fluke Connect
®
app on
your mobile device.
To turn on the radio:
1. Turn on the Product (the radio is off at the initial
power on).
2. Push

to turn on the radio.
When you turn on the radio:
•
