push switch marked ‘V’.

Set power on switch. Adjust the voltage control till the desired voltage is
indicated on the 3-digit DPM. Connect the load at the output. Depress push
switch marked A. The DPM will now read the load current. The total load current
should not exceed 4 Amps for continuous operation.

b) 1504 as Line Leakage Tester.
Set output voltage to ‘O’ volt by turning the knob to minimum position. Depress
push switch marked ‘V’. Set power on switch. Adjust the voltage control till the
desired voltage at which leakage current is to be measured is available at the
output socket, and is indicated on the DPM.

Depress push switch marked ‘mA’. Connect unit under test (U. U. T) to output
socket. Connect U. U. T. earth to banana socket marked ‘leakage test’. The
DPM now reads the leakage current of the unit under test in milliamperes.
