less than 35
Ω (approx.), test current
<0.35mA
Peak Captures peaks >1ms

AC Response True rms
AC True RMS: The term stands for “Root-Mean-Square,”
which represents the method of calculation
of the voltage or current value. Average
responding multimeters are calibrated to
read correctly only on sine waves and they
will read inaccurately on non-sine wave or
distorted signals. True rms meters read
accurately on either type of signal.
ACV Bandwidth 50Hz to 1000Hz
Crest Factor
≤3 at full scale up to 500V, decreasing
linearly to ≤1.5 at 1000V
Display 40,000 count backlit liquid crystal with
bargraph
Overrange indication “OL” is displayed
Auto Power Off 15 minutes (approximately) with disable
feature
Polarity Automatic (no indication for positive); Minus
(-) sign for negative
Measurement Rate 2 times per second, nominal
Low Battery Indication “ ” is displayed if battery voltage drops
below operating voltage
