11 Kewtech recommends the use of fused test leads particularly when
measuring voltages in high energy circuits. Where assessments show
that the risk is significant, then the use of fuse test leads constructed in
accordance with the HSE Guidance Note GS
38 should be used. The test
accessories supplied with this instrument for loop impedance and RCD
tests are all fused.
12 Do not operate the function selector whilst the instrument is connected to
a circuit. If, for example, the instrument has just completed a continuity
test and an insulation test is to follow, disconnect the test leads from the
circuit before moving the selector switch.
13 Do not rotate rotary switch when test button is depressed. If the function
switch is inadvertently moved to a new function when the test button is
depressed or in lock-down position the test in progress will be halted.
14 Always check the test lead resistance before carrying out tests. This
ensures the leads are ok before taking measurements. The resistance
of leads and/or crocodile clips may be significant when measuring
low resistances. If crocodile clips can be avoided for low resistance
measurements, this will reduce the error due to lead accessories.
15 When carrying out Insulation Resistance tests, always release the test
button and wait for charged capacitances to totally discharge before
removing the test leads from the test circuit.
