maximum overload limits per function (see specifications) nor the
limits marked on the instrument itself. Never apply more than 600VDC
between the test lead and earth ground.■ Exercise extreme caution
when: measuring voltage >20V // servicing CRT equipment. ■ Inspect
DMM, test leads and accessories before every use. Do not use any
damaged part. ■ Never ground yourself when taking measurements.
Do not touch exposed circuit elements or probe tips. ■ Do not operate
instrument in an explosive atmosphere.

The DM73B is a probe-type digital multimeter capable of measuring
DC and AC voltage, resistance, diode and continuity. Its controls are:
Volts (V), Ohms ( Ω ), Diode Test and Continuity Beeper ( ), On- Off,
AC/ DC and Hold. (See page 3) 1. V - Ω input. 2. Function selector.
3. HOLD button. 4. SHIFT button for AC / DC or Diode /Continuity. 5.
LCD Display. 6. COM input.
Note: When connecting or disconnecting test leads to or from a circuit,
always first turn off power to the circuit under test and discharge all
capacitors.

DC / AC Voltage Measurement

Set the Function switch to "V". Select AC or DC by pressing the mode
selector button (AC or DC is displayed). Connect the instrument to the
circuit and read the measured voltage in the display.
