6. oil Use an external measuring instrument for better accuracy When testing reactive relays the current coil is to be connected in series with the built in 10mF capacitor that will give a 90 phase shift The voltage coil is to be connected directly to the 110 V AC terminals or across the set of resistors used as a voltage divider 3 Increase the current to the operating value using the variable transformer 4 Check the current on the ammeter or external instru ment during the test ee ee Note Shift polarity of the voltage or current if function has failed to appear Time measurement Connect the time measuring circuit to potential free terminals or DC voltage 3 350 V Note If the polarity is shifted the timer does not stop The timer is independ ent of mains frequency When the timer is stopped the circuit is broken and the yellow signal lamp is lit For continued measuring the main switch first has to be reset in position 0 If the tripping circuit is connected and the switch is set in position ON the yellow signal lamp is lit when the operating value is obtained without breaking the current The timer can be started externally by a make at terminal W3 The switch S1 should then be in position ON TIME or OFF TIME When using the timer internally the terminal W3 has to be short circuited Time measurement of over current and over voltage relays 1 Connect the c
