WARNINGS
To ensure safe operation and service of the meter, follow these instructions.
Failure to observe these warnings can result in severe injury or death.

• Before each use, verify meter operation by measuring a known voltage.

• DO NOT use the meter on a circuit with voltages that exceed the category based rating of this meter.

• DO NOT use the meter during electrical storms or in wet weather.

• DO NOT use the meter or test leads if they appear to be damaged.

• Use ONLY with CAT IV rated test leads.

• Ensure meter leads are fully seated, and keep fingers away from the metal probe contacts when making measurements.

• DO NOT open the meter to replace batteries while the probes are connected.

• Use caution when working with voltages above 25V AC RMS or 60V DC.
  Such voltages pose a shock hazard.

• To avoid false readings that can lead to electrical shock, replace batteries when a low battery indicator appears.

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

• Make sure the circuit under test does not include components that can be damaged by 1000VDC; such devices include power factor correction capacitors, low voltage mineral insulated cables, electronic light dimmers, and ballast/starters for fluorescent lamps.

• DO NOT perform insulation resistance testing or earth-bond resistance testing if voltage is present on parts of an installation or equipment under test. Circuits under test (except for voltage measurements) must be de-energized and isolated before connections are made.

• Circuit connections must not be touched during a test. Accidental contact with conductors could result in electrical shock.

• After insulation resistance testing, make sure the circuit is fully discharged before removing test leads. LCD should read close to zero volts.

• Always adhere to local and national safety codes. Use personal protective equipment to prevent shock and arc blast injury where hazardous live conductors are exposed.

• Meter is IP40 dust & water resistant, except for the test lead jacks.
  Following any contact with water, thoroughly dry meter and test lead jacks prior to subsequent use.

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 CAT III / CAT IV shield increases arc-flash risk.

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

INSULATION RESISTANCE MEASUREMENTS

1. Insert RED test lead into VΩ jack 4 , and BLACK test lead into COM jack 3 , and rotate the function selector to the desired test voltage. Choose from 125V, 250V, 500V, or 1000V based on the compatibility with the device tested. NOTE: Disconnect the circuit under test and isolate it from any stray resistance. Insulation test
   should only be performed on de-energized circuits.

2. Connect the Red and Black leads to the circuit under test. If there is a voltage in the circuit, a constant beep will sound and the Test Voltage symbol will be displayed. Disconnect the circuit to proceed.

3.  Press and hold the TEST button to begin test. The lower right display shows test voltage, and the main display shows the resistance.

4.  The measured insulation resistance is displayed on the main display in MΩ. Allow the reading to stabilize before recording the measurement. Turning the function switch, at any time during the insulation test will end the testing process.

5. The circuit will discharge through the meter. Keep the test leads connected until the circuit is completely discharged and the lower right display shows near zero volts.

NOTE: Measurements can be adversely affected by impedances of additional operating circuits connected in parallel or by transient currents.
NOTE: Overload “OL” for insulation resistance measurements is a value

4000 MΩ.
LOCK FUNCTION
For hands free testing, use the Lock feature for PI (Polarization Index) and DAR (Dielectric Absorption Ratio) testing.
With the test leads connected to the equipment under test, press the “LOCK” button 9 , then press the “TEST” button 10 to begin the test. The lock icon will appear on the display. The meter will beep to indicate it is in lock mode. To end the test at any time during the process, press the “TEST” button 10 , or turn the function switch 2 to any other setting.

AC/DC VOLTAGE MEASUREMENTS

1. Insert RED test lead into VΩ jack 4 , and BLACK test lead into COM jack 3 , and rotate the function selector to the AC Voltage V ∼or DC Voltage setting.
2. Apply test leads to the circuit to be tested to measure voltage.
   NOTE: When measuring DC voltage, the main display shows the voltage measurement, the secondary display shows battery voltage.
   NOTE: When measuring DC voltage, if “–” appears on the LCD, the test leads are being applied to the circuit in reverse polarity. Swap the position of the leads to correct this.

CONTINUITY

1. Insert RED test lead into VΩ jack 4 , and BLACK test lead into COM jack 3 , 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 40Ω, 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.

RESISTANCE MEASUREMENTS

1. Insert RED test lead into VΩ jack 4 , and BLACK test lead into COM jack 3 , and rotate function selector switch 2 to the Resistance setting.
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.
