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 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 CURRENT (LESS THAN 400A)
AC Current is measured by pressing the clamp trigger 10 to open the clamp and placing it around a current-carrying wire. When measuring, care should be taken to ensure that the clamp is completely closed with trigger 10 fully released, and that the wire passes perpendicularly through the center of the clamp in line with the arrow markings 11 .
To measure current:

1. Rotate the Function Selector switch 2 to the 200/400 A setting.

2. Place clamp around wire. The current measurement will be shown in the display.

NOTE:
If the measurement is less than 20A, rotate the Function Selector switch 2 to the 2/20 A setting for improved resolution.

• Disconnect test leads when measuring with the clamp.

AC/DC VOLTAGE (LESS THAN 600V)

1.  Insert RED test lead into VΩ jack 5 , and BLACK test lead into COM jack 4 , and rotate function selector switch 2 to the DC Voltage or AC Voltage setting. Note “DC” or “AC” on the display.
   

2. Apply test leads to the circuit to be tested to measure voltage. The meter will auto-range to display the measurement in the most appropriate range.

NOTE:
If “–” appears on the LCD, the test leads are being applied to the circuit in reverse. Swap the position of the leads to correct this.

• When in a voltage setting and the test leads are open, readings of order mV may appear on the display. This is noise and is normal. By touching the test leads together to close the circuit the meter will measure zero volts.
•  To access mV range for V AC the “RANGE” button 7 must be used.

Manual Mode Sequence

| First Press| Second Press| Third Press| Fourth Press| Fifth Press
---|---|---|---|---|---
AC Range| 0-600V| 0-200V| 0-20V| 0-2V| 0-200mV
DC Range| 0-20V| 0-2V| 0-200mV| 0-600V| 0-200V

NOTE:
When voltages in excess of 25V AC or 60V DC are measured, the Hazardous Voltage Indicator will appear on the display.

RESISTANCE MEASUREMENTS

1.  Insert RED test lead into VΩ jack 5 , and BLACK test lead into COM jack 4 , and rotate function selector switch 2 to the Resistance setting. The resistance symbol will appear on the display.
2.  Remove power from circuit.
3. Measure resistance by connecting test leads to circuit. The meter will auto-range to display the measurement in the most appropriate range.
   

NOTE:
When in a Resistance setting and the test leads are open (not connected across a resistor), or when a failed resistor is under test, the display will indicate O.L. This is normal.

• DO NOT attempt to measure resistance on a live circuit.

CONTINUITY

1. Insert RED test lead into VΩ jack 5 and BLACK test lead into COM jack 4 , and rotate function selector switch 2 to the Continuity setting.
2. Remove power from circuit.
3.  Test for continuity by connecting conductor or circuit with test leads. If resistance is measured less than 10Ω, an audible signal will sound and display will show a resistance value indicating continuity. If circuit is open, display will show “OL”.
   

• DO NOT attempt to measure continuity on a live circuit.
