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

4.2. Verbinding van toetsdrade en toebehore

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. Bedryfsinstruksies

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. Skakel aan/af

Druk die AAN/AF 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. Draai die draaiskakelaar na 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. Druk die TOETS knoppie om die meting te begin.
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. Draai die draaiskakelaar na R_LOW.
2. Connect the test leads to the protective conductor.
3. Druk die TOETS 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).

1. Draai die draaiskakelaar na R_E.
2. Connect the optional earthing kit according to the on-screen diagram.
3. Druk die TOETS knoppie.
4. The earth resistance value will be displayed.

5.5. Loop and Line Impedance Measurement (Z_L-N/L, Z_L-PE)

Measures loop impedance (0.01 Ohm - 10 kOhm) for fault current path and short-circuit current determination.

• Line Impedance (Z_L-N/L): Measures impedance between Line and Neutral or Line and Line, including voltage drop and short-circuit current.
• Loop Impedance (Z_L-PE): Measures impedance between Line and Protective Earth without tripping RCD/FI, including short-circuit current.

1. Draai die draaiskakelaar na Z_L-N/L or Z_L-PE.

Recharge the NiMH batteries when the low battery indicator appears. If the instrument will not be used for an extended period, it is recommended to fully charge the batteries and store the device in a cool, dry place.

6.3. Sekering vervanging

The instrument uses a 0.315 A fuse (part number 757211). If a fuse blows, ensure the instrument is off and disconnected from all circuits before replacing it. Only use fuses of the specified type and rating.

7. Probleemoplossing

• Instrument does not power on: Check battery charge level. Ensure batteries are correctly inserted.
• Onakkurate lesings: Ensure test leads are properly connected and not damaged. Verify the correct measurement function is selected.
• RCD/FI test fails: Check RCD type and nominal current settings. Ensure the RCD itself is functional.
• Display shows "OVERLOAD" or "OL": The measured value exceeds the instrument's range for the selected function. Disconnect immediately.

If problems persist, contact Benning customer support or a qualified service technician.
