4. 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.
4-1. Input Shutter
The Input Shutter inhibits simultaneous connection to the thermocouple jacks and the DMM input jacks.
This is a safety feature which prevents a potentially hazardous condition from existing during high
voltage measurements. Slide the shutter up for test lead measurements or slide it down for thermocouple
temperature measurements.

4-2. Non-Contact Voltage Detector
WARNING: Risk of Electrocution. Before use, always test the Voltage Detector on a known live circuit
to verify proper operation.
1. Rotate the Function switch to any measurement position.
2. Place the detector probe tip on the conductor to be tested.
3. If AC voltage is present, the NCV detector light will turn on with a steady red light.
NOTE: The conductors in electrical cord sets are often twisted. For best results, move the probe tip along a
length of the cord to assure placing the tip in close proximity to the live conductor.
NOTE: The detector is designed with high sensitivity. Static electricity or other sources of energy
NOTE: may randomly trip the sensor. This is normal operation.
4-3. AC/DC Current Measurements
WARNING: Disconnect the test leads before making clamp measurements.
1. Rotate the Function switch to the 1000AAC/DC position
2. Press the MODE button to select AC or DC.
3. Press the trigger to open jaw. Fully enclose only one
conductor.
4. Read the current value in the display.
5. If the value is less than 50A, rotate the function s witch
to the 50AAC/DC position to improve resolution.
DCA Zero
The Zero feature removes offset values and improves
accuracy for DC current measurements.
To perform a zero, select ADC and, with no conductor in the
jaw, press and hold the MODE ZERO button for two beeps.
The display will zero.
The offset value is now stored and removed from all
measurements.
Frequency
When ACV is selected, the measured frequency can be viewed in the lower display.
