SECUTEST with VL2 or VL?

Caution: The VL2 is a universal adapter and works with almost any test instrument. It is not an EL1 type adapter.

Do not use the setting: Verl. Ltg. X WITH EL1. The SECUTEST must be set to: Verl. Ltg. - WITH EL1

Testing with the following devices: SECUTEST 0701/0702S and devices with individual testing, e.g. Metratester 5:

• First carry out a visual inspection as usual.
• Connect the VL2 to the test socket according to the instructions.
• Plug the probe into the socket provided on the VL2.
• Set your instrument to protective conductor test, for SECUTEST 0701/0702S switch setting Menu - RSL and measure the protective conductor resistance. Maximum limit value is 0.3 Ohm for lines up to 5m, or additionally 0.1 Ohm per further 7.5m up to a maximum of 1.0 Ohm.

• Select the insulation resistance measurement RISO function and measure the insulation resistance. The minimum limit value is 1 M Ohm.
• Now turn the rotary switch of the VL2 to position 2 during the insulation resistance measurement. Now an insulation resistance of approx. 10 M OHM (8 to 12 M OHM) must be displayed. This is then the confirmation that the line has no interruptions and no short circuits. In the case of three-phase lines, it is also ensured that no phases are reversed.
• This completes the test.

Testing with the following instruments: SECUTEST 0701/0702SII, SECUTEST 0751/601S, SECUTEST SII(+) and SECUTEST SIII(+):

• Connect the VL2 to the test socket according to the instructions.
• Plug the probe into the socket provided on the VL2.
• Set your instrument to VDE 0702, activate the insulation resistance measurement R-ISO LN-SL X. Deactivate the option Verl. Ltg. - WITH EL1.
• In Setup - Sequence, deactivate the Auto test method option.
• Activate the Manual sequence option X.

• Start the test sequence and work through the test sequence until the insulation resistance measurement.
• Now turn the rotary switch of the VL2 to position 2 during the insulation resistance measurement. Now an insulation resistance of approx. 10 MOhm (8 to 12 MOhm) must be displayed for the VL2 and approx. 7 MOhm (6.3 to 7.7 MOhm for the VL2E. This is then the confirmation that the line has no breaks and no short circuits. With three-phase lines, it is also ensured that no phases are reversed.
• Please note, 10 MOHM is stored as the measured value for the insulation resistance measurement and not the actual value. You should additionally note this fact during such a test.
• After the insulation resistance measurement, you can perform a substitute leakage current measurement; a functional test is not required.
• This concludes the test.
