E140 ammeter, voltmeter E140, E140 milliammeter (E-140, E 140)
 
E140 ammeter, voltmeter E140, E140 milliammeter is designed to measure current and voltage in AC circuits.
Dimensions - 85h85h90mm.
Accuracy class - 2.5.
Resistant to shaking, vibration-resistant, shock-proof.
 
Technical characteristics of the instrument E140 ammeters, voltmeters, E140, E140 milliampemetry:
 
Devices are of conventional (E140) and tropical version (E140T).
E140 ammeter, voltmeter E140, E140 milliammeter used at an ambient temperature of -40 º C to +60 ° C.
Relative humidity - up to 98% (at 60 ° C).
The basic error of measurement devices in the range of less than ± 2,5% (devices such as E140) and ± 1,5% (type devices E140 / 1).
Settling time instrument E140 ammeter, voltmeter E140, E140 milliammeter - up to 3 seconds.
Scale length - 55mm.
In the voltmeter and ammeter type E140 practically uniform scale ranging from 25% to 100% of full scale.
Measurement range and the nominal frequency range of devices E140 ammeter, voltmeter E140, E140 milliammeter are shown in Table.1.
The change of reading due to ambient temperature deviation from the normal for every 10 degrees, no more than ± 0,5% for ammeters, ± 0,8% for voltmeters type E140 / 1, ± 1,0 - for E140.
Changing the readings E140 ammeter, voltmeter E140, E140 milliammeter at frequency deviation of ± 10% of nominal is ± 1,0% for ammeters and does not exceed the basic error for voltmeters;
- Under the influence of an external magnetic field of 400 A / m - not more than ± 2,5%;
- Rejecting an instrument E140 ammeter, voltmeter E140, E140 milliammeter at 45 ° from the vertical position - does not exceed ± 1,0% the length of the measurement range.
