Narrow-profile instruments magneto system with a light indicator designed to measure current and voltage in DC networks, and other electrical, magnetic and non-electrical parameters (if these units are normalized to the value of their testimony in terms of current or voltage), as well as for signaling on the measured value of of given values.
Instruments M1738 ammeter, voltmeter M1738, M1738 microammeter, milliammeter M1738, M1738 kiloampermetr can work complete with regulating device, whose input is consistent with the parameters of photoconductive.
Ammeters and voltmeters are designed to operate at ambient temperatures from -30 º C to +50 ° C and relative humidity up to 100% at 50 ° C.
Instruments M1738 ammeter, voltmeter M1738, M1738 microammeter, milliammeter M1738, M1738 kiloampermetr produced in tropical version will have the designation M1738 ...T2
Modifications of equipment and features of their design:
"Oh, is that all?" he said at last.
- C - Instrument with signal to the filters.
- K - signal to the device with color filters and a photoresistor (three-pin).Signals output from the measured value of the given values ​​to the right and left (on a scale of the instrument).
- KP - Device to signal to the filters and the photoresistor (pin DIP).Signals output from the measured value of the given values ​​to the right (on a scale of the instrument).
- CR - Indicates the output of the measured value of the given values ​​of the left (on a scale of the instrument).
External executive and signaling devices that connect the customer to contact the device devices M1738 ammeter, voltmeter M1738, M1738 microammeter, milliammeter M1738, M1738 modifications kiloampermetr K, KP, CL should be protected from false positives by rapid changes in the measured value, for example, delay in operation of not less than 1s.
Measurement ranges of voltmeters: 0V-1V, 0V-5V, 0V to 10V, 0V-15V, 0V-30V, 0V-50V, 0V-75V, 0V-100V, 0V-150V, 0V-250V, 0V-400V, 0V- 600V.

Instruments M1738 ammeter, voltmeter M1738, M1738 microammeter, milliammeter M1738, M1738 kiloampermetr available and with symmetrical double-sided scales.
Acceptable basic error limit is 1.0%.
Changing the readings ammeter M1738, voltmeter M1738, microammeter M1738, milliammeter M1738, kiloampermetr M1738, caused by: changes in ambient temperature of 20 º C +5 º C to any temperature from -30 º C to +50 ° C with humidity up to 80% less than in every 10 ° C temperature change:
- For the voltmeter and milliammeter - 0.5%;
- For ammeters - ± 0,8%;
- The influence of external magnetic fields of 0.5 mT induction, does not exceed ± 1,0%;
- Changing the position of the device M1738 ammeter, voltmeter M1738, M1738 microammeter, milliammeter M1738, M1738 kiloampermetr at 45 ° from its normal position in any direction shall not exceed 1.0%.
The basic error and change of the readings is expressed as a percentage of full scale measurement range, and for devices with two-scale - from the sum of absolute values ​​of the finite range.
Response time devices M1738 ammeter, voltmeter M1738, M1738 microammeter, milliammeter M1738, M1738 kiloampermetr not exceed 3 seconds.
Dielectric strength 2kV.
Insulation resistance at 20 º C +5 ° C and relative humidity up to 80% - not less than 50 megohms.
Maximum permissible error in contact device actuation devices M1738 ammeter, voltmeter M1738, M1738 microammeter, milliammeter M1738, M1738 kiloampermetr to modify, CC and CL is equal to ± 2% of full scale range.
Output current contact device situated in the devices of modifications to, and CP CR 50mkA (no more) in a dark state and 250mkA (at least) - in an illuminated state when powered from a voltage source of 12V.
