M4230 ammeter, voltmeter M4230, M4230 milliammeter (M 4230, M-4230)
M4230 ammeter, voltmeter M4230, M4230 milliammeter designed to measure current and voltage in DC as mobile and stationary applications.
Dimensions - 40h40h52mm.
Accuracy Class - 4.0.
Devices are tryaskoprochnym and vibration.
M4230 ammeters, voltmeters, M4230, M4230 milliammeter shield used at an ambient temperature of -40 º C to +60 ° C and a relative humidity of 98% (at 35 ° C).
Resistance to mechanical impact devices M4230 ammeter, voltmeter M4230, M4230 milliammeter are shaking and vibration.
To expand the limits of measurement used individual incremental resistance of the type R4200.
Accuracy class instruments M4230 ammeter, voltmeter M4230, M4230 milliammeter - 4.0.
Measuring range milliammeter - 1mA; 5mA; voltmeters - 3/100V; 3/300V; 9/300V; 30/300V (included with an additional resistance-type R103) and 20B.
The voltage drop in less than 600mV milliammeter: to modify the M4230-7 is 66mV, for units of type and M4230-9 - 130mV for the device type M4230-18 - 500mV ± 100mV.
Settling time of mobile devices M4230 ammeter, voltmeter M4230, M4230 milliammeter - less than 3 sec.
Operating position devices - vertical or horizontal.
Change the readings of ammeter M4230, M4230 voltmeter, milliammeter M4230 caused a deviation from the ambient temperature of 20 º C ± 5 ° C (class H) - do not exceed ± 2% for every 10 degrees.
Change the readings does not exceed ± 0,5% in the most unfavorable direction of the magnetic field intensity 400 A / m and when the instrument is in a ferromagnetic shield, as well as under the influence of closely placed with the same instrument.
Weight M4230 devices ammeter, voltmeter M4230, M4230 milliammeter - no more than 0.12 kg.
To mount the unit to the panel frames are built in three bolts.
Gauges are small-sized panel of magnetoelectric voltmeter and milliammeter system with a moving frame and vnutriramochnym magnet.
Measuring instruments ammeter mechanism M4230, M4230 voltmeter, milliammeter M4230 is made with the movable part mounted on the cores.
