Connecting Test Leads and Earth Spikes
Refer to Figure 4 for terminal locations. Connect the test leads to the corresponding terminals (E, ES, S, H) and the auxiliary earth spikes as required for your measurement method.
Operating Instructions
Power On/Off and Backlight
Press the Power/Backlight button (14) to turn the unit on or off. A short press of the same button will toggle the white LED backlight.
Earth Resistance Measurement (RE)
The tester supports both 3-pole and 4-pole methods for earth resistance measurement.
- 3-Pole Method: Press the 3 POLE button (11). Connect the test leads and auxiliary earth spikes according to the diagram in the full user manual.
- 4-Pole Method: Press the 4 POLE button (10). Connect the test leads and auxiliary earth spikes according to the diagram in the full user manual. This method provides higher accuracy by eliminating the resistance of the test leads.
After setting up, press the large orange PRESS TO TEST button (2) to initiate the measurement. The result will be displayed on the screen (7). The device features automatic range detection.
Soil Resistivity Measurement (ρ)
To measure soil resistivity, press the ρEARTH button. This measurement requires setting the interval of auxiliary earth rods (1.0 m ~ 30.0 m). Refer to the full user manual for detailed setup and calculation procedures.
AC True RMS Voltage Measurement (E.V)
Press the E.V button (12) to enter AC voltage measurement mode. The tester can measure AC voltage in the range of 0~50V with a bandwidth of 40Hz ~ 200Hz.
RK Resistance Test
The RK resistance test function (button 13) allows for the removal of line resistance effects from measurements. Consult the detailed manual for specific application instructions.
Earth Comparison Test
This function allows you to evaluate measurement results against a preset "pass/fail" limit. The device will provide audio alarms accordingly. Use the RK/SETUP button (13) to access setup options for this feature.
Automatic Shutdown
The automatic shutdown time can be set from 0 to 90 minutes to conserve battery life. This setting can typically be adjusted via the SETUP function (button 13).
Maintenance
Cleaning
Wipe the instrument with a soft, damp cloth. Do not use abrasive cleaners or solvents. Ensure the device is dry before storage or next use.
Storage
When not in use for extended periods, remove the batteries to prevent leakage. Store the device in its soft carrying bag in a cool, dry place, away from direct sunlight and extreme temperatures.
Troubleshooting
If you encounter issues with your Victor 4106A, consider the following common solutions:
- No Power: Check battery installation and ensure batteries are not depleted. Try using the 15V power adapter.
- Inaccurate Readings: Ensure test leads are securely connected and not damaged. Verify that auxiliary earth spikes are properly inserted into the ground. Check for external electrical interference.
- Display Issues: If the display is dim, activate the backlight. If the display shows "OL" (Over-range), the measured value exceeds the selected range.
- Device Not Responding: Try turning the device off and on again. If the issue persists, remove and reinsert batteries.
For persistent problems, contact customer support or refer to the comprehensive troubleshooting section in the full user manual.
