Connect to the Circuit Under Test
XW Warning
To prevent possible electric shock, fire or personal
injury:
•
Remove all power from the circuit under test and
discharge circuit capacitance before testing a circuit
with the Product.
•
Connect the common test lead before the live test lead
and remove the live test lead before the common test
lead.
•
Before and after testing, confirm that the Product does
not indicate the presence of a hazardous voltage, see
Table 5. If the Tester beeps continuously and a
hazardous voltage is shown on the display, remove
power from the circuit under test and disconnect test
leads.
To connect to the circuit under test:
1.
Move the safety shutter to access the input terminals.
2.
Put the test leads into the correct terminals shown, see Table 6.
3.
Connect the test leads to the circuit under test.
Note
The Tester is NOT specified for <200 kΩ. When the leads are
shorted and a test is performed, the Tester gives an
unspecified reading that is >0. This is normal for this input
circuitry configuration and does not change readings that are
in the specified accuracy range.
