CMM-40
Industrial multimeter 型號:CMM-40
Industrial multimeter CMM-40 was designed for the purpose of measurements of AC/DC voltage, AC/DC current, resistance, capacitance, frequency (electrical and electronic), duty cycle, temperature and also for testing diodes and continuity.
-
The most important features of CMM-40 are:
- autoranging/manual range selection,
- „DATA HOLD” function, for holding measured values,
- „REL” function, which allows you to make measurements relative to a stored reference value,
- „MAX/MIN” function,
- „PEAK HOLD” function,
- memory for 2000 measurement resultS,
- continuity test with acoustic signalling (beeper),
- „AUTO-OFF” function,
- display 4¾ digits (40000 max),
- double molded, waterproof casing.
