Designed to measure the electrical DC resistance.
System ohmmeters M57D - magneto moving part on cores with a pointer to pointer.
Scope: measurement in closed unheated surface and underground areas.
Specifications M57D:
The measurement range is from 20 Ohms to 1500 Ohms.
The internal resistance of the indicator - from 160 Ohms to 250 Ohms.
The basic error, expressed in percent of the measured resistance:
- in the range of 20 Ohm to 80 Ohm, 500 Ohm and 1500 Ohm - not more than ±22%;
- in the range of 80 Ohm to 500 Ohm - not more than ±10%.
The time - 4.
M57D length scale is 40 mm.
Dimensions - 40×72×171 mm.
Ohmmeter weight - not more than 0,4 kg.
An ohmmeter tryaskoprochnym.
Structurally, the indicators M57D decorated in plastic casing, the top of which is the measuring mechanism at the bottom - the power supply.
Operating conditions M57D:
Ambient temperature - from -40° C to +40° C.
Relative humidity at +35° C - 98%.
On the face of the ohmmeter is offset providing circular rotation of the pointer to the mark of "infinity". On the back side located handle magnetic shunt, giving the opportunity to set the pointer to zero scale when you change the voltage from 3.7 V to 4.5 V. On the face side M57D located clamps for connection of the measured resistance.
In stock - 1pc.
