NOTE: Do not use non-rechargeable alkaline batteries with the integrated charging function.

4.2. Connecting Test Leads and Accessories

The device comes with a set of accessories for various measurements.

Figure 4.1: Included accessories: carrying case, test leads, probes, crocodile clips, and rechargeable batteries.

• Connect the test cable with the protective contact plug for standard outlet measurements.
• For other measurements, use the 3-conductor universal cable (1.5 m length) with the provided test probes or crocodile clips as required by the specific test.
• Ensure all connections are secure before performing any tests.

5. Operasyon Enstriksyon

The Benning IT 115 offers a range of measurement functions accessible via the rotary switch and control buttons. The graphic display provides clear readings and a help function with connection diagrams.

5.1. Powering On / Off

Peze a ON/OFF button to switch the instrument on or off.

5.2. Insulation Resistance Measurement (R_ISO)

Measures insulation resistance between 0.01 MOhm and 1000 MOhm.

1. Vire switch la Rotary nan R_ISO.
2. Select the desired nominal test voltage (50V, 100V, 250V, 500V, 1000V) using the navigation buttons.
3. Connect the test leads to the circuit under test as indicated by the on-screen help diagram.
4. Peze a TÈS bouton pou kòmanse mezi a.
5. The result will be displayed, and the green/red LEDs will indicate pass/fail based on set limits.

5.3. Low-Ohm Resistance Measurement (R_LOW)

Measures low resistance from 0.01 Ohm to 2000 Ohms, typically for protective conductor continuity.

1. Vire switch la Rotary nan R_LOW.
2. Connect the test leads to the protective conductor.
3. Peze a TÈS button. The instrument uses a 200 mA test current with polarity reversal and a 7 mA test current for continuity.
4. Observe the displayed resistance value.

5.4. Earth Resistance Measurement (R_E)

Measures earth resistance using the 3-conductor method (requires optional earthing kit 044113).
