CMP-402 / 403 True RMS multimeter is intended for measuring di-
rect and alternating voltage, direct (
rent, resistance, capacitance, frequency, duty cycle (filling) and
temperature and for testing diodes and circuit continuity.
The most important features of CMP-402 / 403 include:
possibility of carrying out measurements in the output cir-
cuits of inverters and frequency converters,
non-contact voltage detector,
automatic and manual range setting,
REL function for relative measurements,
PEAK MAX/PEAK MIN function for displaying maximum and min-
imum peak values,
the INRUSH function captures the starting current precisely in the
beginning of 100-millisecond period when the device is just started,
HOLD function used to maintain the read-pot on the me-
ter screen,
backlight of the screen to read the measurement results in
poor light,
built-in flashlight for lighting the measurement location,
sound signal for circuit continuity,
AUTO-OFF function,
4-digit display (read-out 4000).
