Page 5: Operation
Operation NOTES: Read and understand all Warning and Caution statements in this operation manual prior to using this meter. Set the function select switch to the OFF position when the meter is not in use. Non-Contact Voltage Detector WARNING: Risk of Electrocution. Before use, always test the Voltage Detector on a known live circuit to verify proper operation. - Page 6 AC/DC Voltage, Frequency, Duty Cycle Measurements CAUTION: Do not measure voltages if a motor on the circuit is being switched ON or OFF. Large voltage surges may occur that can damage the meter. Rotate the function switch to the V position. Press the MODE button to select AC or DC Voltage.
- Page 7 Capacitance Measurements WARNING: To avoid electric shock, discharge the capacitor before measuring. Rotate the function switch to the CAP capacitance position. Insert the black test lead banana plug into the negative COM jack. Insert the red test lead banana plug into the positive CAP jack. Touch the black test probe tip to one side of the device.
- Page 8 Data Hold To freeze the LCD reading, press the HOLD button. The HOLD icon appears on the LCD. Press the HOLD button again to return to normal operation. Relative Press the REL button (REL will appear in the display) to zero the reading and create a reference point.
