Safety Information

• Read all safety information carefully before attempting to operate or service the meter.
• Do not use the Tester around explosive gas, vapor, or in damp or wet environments.
• Keep fingers behind the finger guards on the probes.
• The circuit under test must be de-energized and isolated before connections are made except for voltage measurement.
• Circuit connections must not be touched during a test.
• After insulation test, capacitive circuits must be allowed to discharge before disconnecting the test leads.
• To avoid damage to the instrument, do not apply signals which exceed the maximum limits shown in the technical specification tables.
• Do not use the meter or test leads if they look damaged. Use extreme caution when working around bare conductors or bus bars.
• Use the meter only as specified in this manual; otherwise, the protection provided by the meter may be impaired.
• Caution when working with voltages above 30 Vac rms, 42 Vac peak, or 60 Vdc. Such voltages pose a shock hazard.
• Before taking resistance measurements or testing continuity, disconnect the main power supply and all loads from the circuit.
• Remove all probes, test leads, and accessories before the battery door is opened.
• Replace the batteries when the low battery indicator shows to prevent incorrect measurements. False readings can lead to electric shock and injury.
• Replace all batteries with fresh batteries of the same manufacturer and type to prevent battery leakage.
• Remove the batteries if the Tester is not used for an extended period of time, or if stored in temperatures above 50 °C. If the batteries are not removed, battery leakage may result.

CAUTION!

• Disconnect the test leads from the test points before changing the position of the function rotary switch.
• Never connect a source of voltage with the function rotary switch in Ω, LoΩ, 50V, 100V, 250V, 500V, 1000V position.

Making Measurements

• Measuring Volts:
  Press the blue button to switch ACV or DCV measurement.

• Measuring Ohms / Continuity:
  Press the blue button to select the measuring function.

Measuring Low Resistance:
The circuit under test must be completely de-energized. Check the fuse before testing. See Testing the fuse section later in this manual. Connecting the tester to an energized circuit while the test is active will blow the fuse.

1. Short the end of probes together and press the blue button to compensate the probe resistance for 2 Ω , the “zero ” symbol will be displayed when the compensating is finished. The range of compensation needs to be less than 2 Ω. The value of compensation will be kept next time you use this function.
2. Connect the probes to the circuit to be measured. The Tester automatically detects if the circuit is energized. If the detected voltage is above 2V, ” > 2V ” and “ ” will appear on the LCD display. In this condition, the test is inhibited. Disconnect the Tester and remove power before proceeding.
3. Push and hold button to start the test. The “ ” symbol appears on the LCD display until you release the button. The resistance reading appears on the primary display until a new test is started or a different function or range is selected. If it beeps 4 times, means the tester has not finished the terminal voltage test. You need to start the test again.

If you press button to enter the Lock Mode, and then press button to start the test. The“ ” symbol appears on the LCD display and the test voltage will continue to be applied until the or button is pressed again.

When resistance is higher than the maximum measuring range, the Tester displays the “ ” symbol and the maximum resistance for the range.

Measuring PI / DAR:
Polarization Index (PI) is the ratio of the 10-minute insulation resistance to the 1 -minute insulation resistance. Dielectric Absorption Ratio (DAR) is the ratio of the 1-minute insulation resistance to the 30 second insulation resistance.

1. Turn the rotary switch to the desired test voltage.
2. Press the button to select polarization index or dielectric absorption ratio.
3. Press button to start the test. During testing, the primary display shows the measured resistance and the secondary display shows the test voltage applied to the circuit under test.

When the test is completed, the PI or DAR value is displayed on the primary display. If either value used to calculate PI or DAR was greater than the maximum measuring range, the primary display will show “ Err ” for PI or DAR value. Because of the time required to perform the PI and DAR tests, use of test clips is recommended. To interrupt a PI or DAR test before it is completed, momentarily press .

Testing Fuse

Warring!
To avoid electrical shock or injury, remove the test leads and any input signals before replacing the fuse.

1. Turn the rotary switch to the position.
2. Press and hold . If the display reading is “ ”, the fuse is bad and should be replaced.

Replacing Batteries & Fuse

Warring!
To avoid shock, injury, or damage to the Tester:

• To avoid false readings, which could lead to possible electric shock or personal injury, replace the batteries as soon as the battery indicator “ ”appears.
• Use ONLY fuses with the amperage, interrupt, voltage, and speed ratings specified.
• Turn the rotary switch to OFF and remove the test leads from the terminals.
  • Fuse rating : Fast 315mA, 1000V, Min Interrupt Rating 10000 A
  • Battery : 1.5 V AA alkaline (NEDA 15A, IEC LR6) x 4 pcs
