In manual range, ‘OL’ is displayed when overload occurs. Choose a higher range if possible to acquire correct reading. To perform measurement, first connect the test lead to common (COM), then connect the probe tip of the Meter to the circuit to be tested. ...
chosen by pressing the “RANGE” button. Hold “RANGE” to go back to Auto range. Connect the probe tip of the Meter and tip of the test lead (or test clip) across the power source or load. Read the measurement from LCD display. The polarity of the Meter’s probe will be indicated.
Insert the black test lead or test clip in the “COM” jack. Set the rotary switch to the “mA ” position. Press the "FUNC.F" button to switch between DC and AC measurements. Manual range can be chosen by pressing the “RANGE” button. Hold “RANGE”...
Set the rotary switch to the “” position. Manual range can be chosen by pressing the “RANGE” button. Hold “RANGE” to go back to Auto range. Connect the tip of the Meter probe and test lead (or test clip) across the resistance or circuit under measurement and read of the reading from LCD.
NOTE: The Meter shows the forward voltage drop. If the lead connection is reversed, “OL” is displayed. Continuity WARNING TO AVOID ELECTRICAL SHOCK AND INJURY POWER OFF THE CIRCUIT AND DISCHARGE THE CAPACITANCE BEFORE MEASURING CONTINUITY. Rotate the probe knob clockwise to extend the probe from the Meter.
Logic Test NOTE: The logic test will only work for 5V Signals. Make sure the retractable probe is stored back in the Meter. Insert the black test lead or test clip in the “COM” jack. Set the rotary switch to the “LOGIC” position. ...
Data Hold To hold the reading of a measurement, press “DATAH” button once. “D.H” will appear on the LCD, reading will be held. Press again to cancel holding value. Maximum and Hold To show the maximum value of the measurement and hold that value, press “MAX.H”...
