Microammeter M136, millivoltmeter M136, voltmeter M136,  galvanometer M136 (M 136, M-136, m136, m 136, m-136)
Ammeter, voltmeter and millivolt M136 M136A and designed to measure the dc current and voltage.
Galvanometer M136 / M136 1 and / 2 are designed to measure voltage and current zero method.
Panel-mounted instrument system with a light pointer. ammeter, voltmeter and millivoltmeters M136 and M136A designed to measure the dc current and voltage. Galvanometers M136/1 and M136/2 are used to measure voltage and current zero method.
M136 device is designed to operate at ambient temperatures from -10 to +60 ° C and relative humidity up to 95% at +30 ° C.
Technical data
Parameters microammeter, millivolt and voltmeters are given in Table. 1. Galvanometer parameters are given in Table. 2.
Note.
Special order can be made:
a) instruments with a bilateral scale (halving of any of these in Table 1. limits, except for 45 and 75 mV);
b) mnogopredelnye shunts P26 microamperometer 0.5 uA, extend the measuring range of up to 10 mA.
Failure to return the pointer device M136 to the zero point of the scale with a smooth traverse a pointer to that point from the extreme of the scale does not exceed 0.5 mm. Dielectric strength 2kV devices. Insulation resistance of the device M136 normally not less than 10 9 ohms.
Lighting pointer is an incandescent lamp 2.5 V, 2 watts. Illuminator lamp is powered by a DC or AC voltage of 2.5 V or AC voltage of 127 or 220 via a separate transformer. The length scale of the instrument M136 at least 120 mm, galvanometer scale is divided into 120 divisions.
Dimensions: M136 device not more 160h80h140 mm shunt maximum 120h150h85mm; transformer max 136h65h65 mm. Weight of the device M136 is not more than 1.0 kg.
