PrimeTest 100 Operating Instructions

• If the Insulation Resistance is greater than the
factory set limit a tick is placed next to the
Riso enunciator. Similarly, if the Leakage
current is less than the factory set limit a tick is
placed next to the I
LEAK
enunciator.
• The PASS enunciator is illuminated.
3.4 Testing a mains cord
• Visually inspect the mains cord and plug for
signs of damage.
• Check that the correct fuse is fi tted.
• If the cord passes a visual inspection proceed
with the electrical tests.
• Plug the mains cord under test into the IEC
socket and the front panel mains socket on
the PrimeTest 100.
• Press the cords test key
•
The PrimeTest 100 will fi rst test the continuity of
the protective earth.
• If the measured value is greater than the factory
set limit a cross is placed next to the R
PE
enunciator, a FAIL is indicated.
Note: The protective earth resistance will
depend upon the length of the extension
lead and the size (cross sectional area)
of the cable. The measured value may
be acceptable even if a cross is
shown next to the R
PE
enunciator.
For reference, typical resistance values
for a variety of cable lengths and
cross-sectional area are given in Table 1.
