Connect UUT the output terminals. In STANDBY mode the calibrator waiting for test voltage. When valid test voltage identified the output terminals, the calibrator goes over RUNNING statue. Use test leads delivered with UUT whenever possible. 2:-; Fig. Select resistance range UUT necessary. 11.0 £ Umax:0 .002 Mode: TIMER ACCURACY 0 'T/ Fig.229kU OFF Local Grid Test, 11a'EJe: Mode : TIMER ACCURACY 0.
