Weight 631 g
Dimensions 220 x 96.5 x 60.5 mm
Diode test Test current of 0.9 mA maximum, open
circuit voltage 2.8 VDC typical
Continuity check Audible signal will sound if the resis-
tance is less than 35 Ω (approx.), test
current < 0.35 mA
Peak Captures peaks >1 ms
Input impedance >10 MΩ VDC & > 9 MΩ VAC
AC response True RMS
AC True RMS The term stands for Root-Mean-Square,
which represents the method of calcu-
lation 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 50 Hz....1000 Hz
Crest factor ≤ 3 at full scale up to 500 V, decreasing
linearly to ≤ 1.5 at 1000 V
