5. Instruccions de funcionament

The BENNING IT 105 offers various measurement functions. Always select the correct function for the test required.

5.1. Low-Resistance Measurement (Continuity Test)

This function measures the low-resistance of protective earth conductors and equipotential bonding conductors with a test current of 200 mA.

1. Turn the rotary switch to the continuity test symbol (e.g., Ω).
2. Connecteu els cables de prova al circuit que es prova.
3. Premeu el botó PROVA botó per iniciar la mesura.
4. Llegiu el valor de resistència a la pantalla.

5.2. Mesura de la resistència d'aïllament

Measures insulation resistance with selectable test voltages of 250 V, 500 V, and 1000 V.

1. Turn the rotary switch to the Riso position.
2. Use the function buttons (F1-F4) to select the desired test voltage (250 V, 500 V o 1000 V).
3. Connect the test leads to the conductors between which insulation resistance is to be measured.
4. Premeu el botó PROVA button. The measurement will be displayed.

5.3. Loop Impedance Measurement (Zs/Zi)

This function measures loop impedance (L-PE) without tripping RCDs (NO-TRIP) and simultaneously displays the prospective fault current (PFC). It also measures line impedance (L-N/L) with a high test current (HIGH CURRENT) and displays the prospective short-circuit current (PSC).

1. Turn the rotary switch to the Zs/Zi position.
2. Select either NO-TRIP (for RCD protected circuits) or HIGH CURRENT (for non-RCD protected circuits) using the function buttons.
3. Connect the test leads to the appropriate points in the circuit (e.g., L-PE for loop impedance, L-N or L-L for line impedance).
4. Premeu el botó PROVA button. The impedance and corresponding fault/short-circuit current will be displayed.

5.4. Prova de RCD

Tests RCDs (Residual Current Devices), including standard and delayed (S) types, with sinusoidal (AC) and pulsating (A) test currents.

1. Turn the rotary switch to the RCD position.
2. Use the function buttons to select the RCD type (AC or A), nominal tripping current (e.g., 30mA, 100mA), and test current multiplier (x1/2, x1, x5).
3. Connect the test leads to the circuit protected by the RCD.
4. Premeu el botó PROVA button. The device will perform the test and display the tripping time and current.

6. Manteniment

6.1. Neteja

Netegeu el dispositiu regularment amb un drap suau iamp cloth. Do not use abrasive cleaners or solvents. Ensure the device is powered off and disconnected from all circuits before cleaning.

6.2. Substitució de la bateria

Replace batteries when the low battery indicator appears on the display. Refer to section 4.1 for battery installation instructions. Dispose of used batteries according to local regulations.

6.3. Emmagatzematge
