USE
Before switching on, screw in the two antennae.
Push button operation:
To switch on, press the push button in until the SOFAMEL logo appears on the screen.
Short press = Move (the right of the screen shows
Long press = Accept (the right of the screen shows
Keep pressed for approx. 8 seconds = RESET.
1. Test menu:
After accepting, the detector checks the screen, the LEDs and the speaker, and goes into standby ready to check the detector is fully
operational, using the external tester by placing the electrodes against a live cable to complete the test.
2. Measuring mode:
The measuring mode can check for and measure voltage with a tolerance of ±10%. (To check the voltage between phase and neutral,
place the pole with the detector on the phase and the other pole on the neutral/earth for greater accuracy.)
3. Matching mode:
Matching mode can identify whether or not the cables touched with the poles belong to the same phase.
Before using this mode the device needs to be calibrated for the line voltage being tested. The detector screen will indicate the
instructions to follow for correct calibration. The two poles must first be put into the same phase, a few seconds elapse before the
reading is made, at which point a beep will sound to confirm the reading. It will then indicate to measure earth/neutral phase, or accept
by pressing the button. If measuring the earth/neutral phase, place one of the two poles touching ground, and a beep will sound to
confirm the reading.
When reading the same phase, the detector beeps and the screen flashes green while displaying the message "MATCHED PHASE". If
touching two cables with different phases, the detector will show a continuous red light and the screen will display the message
"MISMATCHED PHASE". Finally, if the message "INDUCED VOLTAGE" appears, it means that the tester is detecting a voltage that is lower
than expected.
4. Network analysis mode:
This mode allows the particular network voltage of to be chosen and shows the maximum and minimum voltages that may be encountered
based on the actual voltage measured.
5. Configuration menu:
This menu appears the first time that the device is switched on. The language used to operate the detector can be chosen here.
6. Statistics menu:
The first page shows the total time that the detector has been switched on, the number of times the test has shown as correct and the
number of times it has shown as incorrect.
The second page shows the highest voltage measured by the detector since it was switched on and the highest voltage read in the last
session.
7. Help menu:
The first page shows the manufacturer's contact information. The second page shows information on the battery. The third page
shows how to reset the detector. The fourth page shows the detector's operating voltage.
8.OFF:
Switches the device off.
MAINTENANCE
In case of strange operating, contact SOFAMEL, S.L.
Do not manipulate the device because can affect the correct operating and the loose of the guarantee.
After each use, keep the pole and detector inside its transport bag.
Even if it is stored, the voltage detector should be checked and calibrated by the manufacturer after a maximum of 6 years.
BATTERY CHANGE
To change the battery, a screwdriver is required.
Unscrew the four screws on the back cover.
Replace the battery.
