Digital microohmmeter MOM 6-200-01D
Microohmmeter digital is designed to measure low resistances in the range of 0,01 mOm to 400 mOm (contact resistance of switches, sockets, fuse blade terminals, bus connections, line connections, etc.) at the output 6 V voltage and current up to 200 A, as well as for the process run these elements.
Measurement of the resistance value is realized by a 4-clamping manner and is independent of the resistance measuring wire. Resistance measurement is not more than 0,5 sec and displayed on a digital LCD display with a resolution of 0,025%, but unlike the prototype may continue until such time as there is a change in resistance.
Attention! Microhmmeter can be a long time to measure the contact resistance at the output current is 200A, which allows the oil to break or an oxide film on the contacts, you can not do microhmmeter low output current, or even a short-term high current.
After the measurement session, all sessions can be viewed on a computer by connecting a cable USB. The measuring range of resistance and the desired output current is given from the keyboard. By electromagnetic interference (EMI) device complies with EN55022.
The device is designed to operate in a temperate climate with temperature the external environment of -20 to +40 °C and relative humidity to 80 % plus 25 °C.
Distinctive features:
- continuous operation at a maximum current 200 A;
- automatic switching on (off) fans;
- thermal protection;
- highly reliable and fire safe;
- shock-rugged design that allows measurements in laboratory and on-site.
