OPERATING INSTRUCTIONS

CONNECTING TEST LEADS
Do not test if leads are improperly seated. Results could cause intermittent display readings. To ensure proper connection, firmly press leads into the input jack completely.

TESTING IN CAT III / CAT IV MEASUREMENT LOCATIONS
Ensure the test lead shield is pressed firmly in place. Failure to use the CATIII / CATIV shield increases arc-flash risk.

TESTING IN CAT II MEASUREMENT LOCATIONS
CAT III / CAT IV shields may be removed for CAT II locations. This will allow testing on recessed conductors such as standard wall outlets. Take care not to lose the shields.

AC/DC CURRENT (LESS THAN 600A)
AC Current is measured by pressing the clamp trigger 10 to open the clamp 3 and placing it around a current-carrying wire. When measuring, care should be taken to ensure that the clamp 3 is completely closed with trigger 10 fully released, and that the wire passes perpendicularly through the center of the clamp 3 in line with the arrow markings 11 .

NOTE: Current measurement can be made by clamping around single conductors, but not cables containing both live and neutral wires. In this case a line splitter is required, Klein Cat. No. 69409 is recommended.

To measure current:

1. Rotate the Function Selector switch 2 to the AC/DC current A setting.
   NOTE: The meter defaults to AC measurement. Press the “SEL” button 9 to toggle between AC and DC modes. The AC or DC icon on the LCD indicates which mode is selected.

2. Place clamp 3 around wire. When measuring DC current, align the polarity markings 15 on the clamp with the polarity of the wire to avoid negative readings. The current measurement will be shown in the display. The meter will auto-range to display the measurement in the most appropriate range.

Disconnect test leads when measuring with the clamp.
NOTE: If non-zero values are displayed prior to measuring in DC current mode, an offset correction is required. With meter in DC current mode, press and hold the “SEL” button 9 to activate the DC current ZERO function. Subsequent DC current measurements automatically subtract the offset correction for improved accuracy.

AC/DC VOLTAGE (LESS THAN 1000V)
