Stopwatch electric P14-2M (P 14-2M, P-14-2M, P14 2M, P142M)
Is a table electromechanical device designed to measure the time intervals ranging from 0.1 seconds to 10 minutes. Between opening and closing the electric circuit contact.
Limits of measurement for time scales:

hundredths of a second 0-1s;
second 0-1 min;

0-10 min minute.
The error of measurement of time intervals with ± 0,01


Stopwatch electric type A14-2M board are electromechanical devices used for measuring time intervals ranging from 0.1 seconds to 10 minutes. between the opening and closing an electric circuit contacts. Installing the shooter to zero by pressing a button located on the body of a stopwatch.
Main technical characteristics
Terms of use of the appliance stopwatch electric P14-2M:
a) ambient temperature 1 to 40 ° C;
b) Relative humidity 80% at 25 ° C;
c) the position of the scale with an inclination from vertical to 5 °.
Limits of measurement for time scales:
hundredths of a second 0-1s;
second 0-1 min;
0-10 min minute.
The error of measurement of time intervals should not exceed:
a) for feeding the synchronous motor voltage AC 220 ± 22 stabilized at 50 ± 5.10 -5 Hz at intervals of 0.1 seconds to 1 minute ± 0,01 s at intervals of 1 minute to 10 minutes ± 0,015 c;
b) when powered synchronous motor voltage AC 220 ± 22 with the stabilization of the frequency of 50 Hz ± 5.10 -5
± (0,015 + ΔF / F · T) s, where 0,015 - constant error component, F - the nominal frequency of the supply voltage synchronous motor (50 Hz); ΔF - frequency error voltage    Power synchronous motor, T - measured time interval p.
Power supply:
a) synchronous electric motor - AC 220 V ± 22 V stabilized frequency 50 Hz ± 5.10 -5;
b) an electromagnet - AC 220V +22 / -33 V and 50 Hz ± 0,5.
Nominal power consumption of no more than:
a) motor - 4 BA;
b) an electromagnet - 8 VA.
The insulation resistance of electrical circuits to each other and relative to the body of at least 10 MW.
Size not more-125X140X100 mm. Weight of not more than - 1.1 kg.
