cymometer F291
|
Frequency & nbsp; F291 & nbsp; is intended to measure the timing relay power relay coils from the external DC source 10 at a voltage up to 240 V; variable up to 6 A frequency of 50 Hz at a voltage of up to 380, and in the absence of the instrument connecting to an external power source relay coils.
devices used for the repair and maintenance of the relay automation systems of power plants and substations, and also for measuring parameters of different types of mechanical switches, toggle switches, buttons
Main characteristics:. The instrument can measure the first circuit (open) contact inspected relay following timing when powered relay coils from the external power source: activation time of the relay with normally open or normally closed contacts; time relay is released; difference in response time (releasing) any combination of two pairs of contacts. The device allows to measure the following temporal parameters of the relay with the vibration of the contact during feeding relay coils from the outside DC or AC: D response time le to make or break contacts;. release time relay with normally open or normally closed contacts The instrument can measure in the absence of the instrument connecting to an external power source relay coils difference circuit time (opening) any combination of two pairs of contacts. The device allows to measure time short-circuiting or opening the contact. The instrument provides a measurement of the time intervals to 100,000 msec. accuracy instrument 0,005 / 0,004. The device has a five-digit digital readout additional indication overflow counter operative to store indications and manual reset. The device output is provided to an external connector reading device reading values in BCD 8-4-2-1 The supply voltage 220 (+ 10, -15)% V (50 & plusmn; 1). Hz <. / p> power consumption 20 VA operating conditions: ambient temperature of minus 10 to 50 & deg; C. relative humidity 90% at 30 & deg;. C. Dimensions, mm 134 x 210 x 270 Weight, kg 4,0 ..
