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.
Parameters microammeter, millivolt and voltmeters are given in Table. 1. Galvanometer parameters are given in Table. 2.
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.
Graduation for current and voltage, internal resistance, the period of free oscillations should not vary on the scale of more than ± 10%, and the external critical resistance galvanometer - by more than ± 20%.
Deviations of the galvanometer pointer difference on either side of the zero mark of the scale at the same currents of less than 5% of the mean deviation.
