Then discharge all capacitors of the circuit. Break the circuit path to be measured, and connect the test leads in series with the circuit. Turn on power to the circuit. • 052-0060-2 contact us 1-800-689-9928 When the input is not connected, i.e. At open circuit, '1' will be displayed as an overrange indication.

Before measuring in-circuit resistance, disconnect all power to the circuit to be tested and discharge all capacitors thoroughly. • Connect the red test lead to the anode of the diode to be tested and the black test lead to the cathode of the diode. The display will show the approximate forward voltage drop of the diode. If the connection is reversed, '1' will be shown on the display. • 052-0060-2 contact us 1-800-689-9928 MAINTENANCE Warning Except replacing fuse and battery, never attempt to repair or service the meter.
