The device has a 10000 counts LCD display and push buttons for features. The rotary switch is used to turn the power on/off and select the desired insulation function. The device is equipped with double or reinforced insulation and conforms to EU directives. The device has a test voltage range of 50V / 100V / 250V / 500V / 1000V.

Product Usage Instructions

Preparation and Caution Before Measurement: Observe the rules, warnings, and cautions. When connecting the test leads to the DUT (Device Under Test), connect the common (mA) test lead before connecting the live lead; when removing the test leads, remove the test live lead before removing the common test lead.

Measuring AC/DC Voltage: Turn the rotary switch to the desired voltage measurement position. Connect the probes to the circuit and read the voltage value on the LCD display.

Measuring Resistance/Continuity/Diode: Press the blue button to select the desired measuring function. For diode testing, connect the probes to the diode and read the value on the display. For continuity testing, use the buzzer, which sounds when a short (<30) is detected.

Measuring Capacitance: Turn the rotary switch to the capacitance measurement position. Connect the probes to the circuit and read the capacitance value on the LCD display.

Measuring AC/DC Current: Turn the rotary switch to the desired current measurement position. Connect the probes to the circuit and read the current value on the LCD display.

Measuring Insulation Resistance: Before testing, check the fuse (see page 19 for how to check the fuse). To measure insulation resistance, follow these steps:

1. Insert test probes in the + and – input terminals.
2. Turn the rotary switch to the insulation position.
3. Press the orange button to select the test voltage.
4. Connect the probes to the circuit.
5. Push and hold the Test button to start the test. The Test and Ω appear on the display. The secondary display shows the test voltage applied to the circuit under test. The primary display shows the resistance.
6. Keep the probes on the test points and release the Test button. The resistance reading appears on the primary display until a new test is started or a different function or range is selected or >30 V is detected.

Note: Insulation tests should only be performed on dead circuits.

Safety Information

Understand and follow operating instructions carefully. Use the meter only as specified in this manual; otherwise, the protection provided by the meter may be impaired.

Warning

Identifies hazardous conditions and actions that could cause.

BODILY HARM or DEATH

• When using test leads or probes, keep your fingers behind the finger guards.
• Remove the test lead from the Meter before opening the battery door or Meter case.
• Use the Meter only as specified in this manual or the protection by the Meter might be impaired.
• Always use proper terminals, switch positions, and range for measurements.
• Verify the Meter’s operation by measuring a known voltage. If in doubt, have the Meter serviced.
• Do not apply more than the rated voltage, as marked on the Meter, between terminals or between any terminal and earth ground.
• Only replace the blown fuse with the proper rating as specified in this manual.
• Use caution with voltages above 30 Vac rms, 42 Vac peak, or 60 Vdc. These voltages pose a shock hazard.
• To avoid false readings that can lead to electric shock and injury, replace the battery as soon as the low battery indicator blinks/appears.
• Disconnect circuit power and discharge all high-voltage capacitors before testing resistance, continuity, diodes, or capacitance.
• Do not use a Meter around explosive gas or vapor.
• To reduce the risk of fire or electric shock do not expose this product to rain or moisture.
• Probe assemblies to be used for MAINS measurements shall be RATED as appropriate for MEASUREMENT CATEGORY III or IV according to IEC 61010-031 and shall have a voltage RATING of at least the voltage of the circuit to be measured.
• Never attempt a voltage measurement with the test lead inserted into the INSULATION input terminal.
• Avoid working alone so assistance can be rendered.
• Do not use the Tester if the Tester is not operating properly or if it is wet.
• Individual protective devices must be used if hazardous live parts in the installation where the measurement is to be carried out could be accessible.
• Do not attempt a current measurement when the open voltage is above the fuse protection rating. Suspected open voltage can be checked with the voltage function.
• Never attempt a voltage measurement with the test lead inserted into the A input terminal.

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, °C, mA, INSULATION position.
• Do not expose the Meter to extremes in temperature or high humidity.

Never set the meter in, the mA, INSULATION function to measure the voltage of a power supply circuit in equipment that could result in damage to the meter and the equipment under test.

Symbols as marked on the Meter and Instruction manual
