TKL3655 FDM Adaptor Tester, Non-Intrusive
Ref: 0040/001004
£192.00 excl. VAT £230.40 inc. VATThe adapter’s Green lead should be connected to the test earth and the Red lead shall be connected to the cable under test, normally on the cable terminals. The voltage reading (v) on the multimeter should be allowed to steady before being noted.
The Red lead should then be connected to the test terminals in the order shown below. The reference readings do not require any stabilising time and should be performed using the same multimeter within a short period (three minutes) of the cable test.
Terminal Reference Value (Mega Ω)
White 1M
Brown 3M
Yellow 6M
Green 10M
Blue 15M
For each of the reference terminals the voltage observed should be compared against the voltage observed on the cable (v). The reference voltage will be seen to go steadily lower as the reference resistance value increases. When the reference terminal voltage is lower than the cable voltage (v), the cable leakage resistance is lower than that reference value.
