Page 2: Read First: Safety Information
Read First: Safety Information To ensure that the tester is used safely, follow these instructions: Do not use the DMM if the tester or test leads appear damaged or if you suspect that the DMM is not operating properly. Disconnect the live test lead before disconnecting the common test lead. When using the test leads, keep your fingers behind the finger guards on the test leads. -

safeguards within this equipment. 1. Automatic Selection Insert the red test lead to the “V/OHM” jack, and the black test lead to the “COM” jack. When turned on, the DMM powers up in SCAN mode.”SCAn” will appear in the LCD. Test the object by 2 test leads, you’ll get the tested AC, DC voltages or resistance. -
Page 4: Resistance Measurement
Resistance measurement Refer to Automatic Selection. Without exterior voltage, the DMM shifts to resistance measure mode when the resistance in the input terminal is below 40M . The tested resistance will be shown with figures, accompanying corresponding units ，k or M . In resistance measure mode, do not impose voltage on the test resistance or it may be damaged or operated incorrectly. -

value will not exist any more. It begins at 0V to measure the voltage range. DC and AC Current measurement Refer to Automatic Selection. When the current is above 5mA, the DMM enters current measure mode automatically. The LCD will indicate the current with DC or AC and its shown with figures in the corresponding units A or mA Warning To avoid damage to the meter or injury if the fuse blows, never attempt an in-circuit current measurement where... - Page 6 In auto selection status, “Just one key selects the measurement function” mode happens if this key is pressed when “SCAn” appears in the LCD. Continuously press this key, DMM will exit the status of auto selection and then enter the specific measure mode, DCV, ACV, OHM, Diode, Continuity, Capacity, SCAN can be selected in turn. “SCAn” appearing in the LCD means it returns to auto selection mode.

Page 8: Capacitance Measurement
Connect the black test lead to "COM" socket and red test leads to the "V Hz" socket. Press SELECT button to “ ” or “ ” , ” ” position. Connect the probes across circuit to be tested. Caution: Ensure that the circuit to be tested is "dead". (no live voltage present) Capacitance measurement Before testing, discharge the capacitor by shorting its leads together. -
