Safety Information
XW Warning: Read before Tester use.
To prevent possible electrical shock or personal
injury, follow these guidelines:
• Before and after testing, confirm that the Tester
does not indicate the presence of a hazardous
voltage, see Figure 3. If the Tester beeps
continuously and a hazardous voltage is shown
on the display, remove power from the circuit
under test or allow the installation capacitance to
fully discharge.
• Use the Tester only as specified in this manual.
Otherwise the protection provided by the Tester
can be compromised.
• Connect the common test lead before the live test
lead and remove the live test lead before the
common test lead.
• Do not disconnect the test leads before a test has
been completed and the test voltage at the
terminals has returned to zero. This ensures that
any charged capacitance is fully discharged.
• Disconnect circuit power and discharge all high-
voltage capacitors before you measure resistance
or capacitance.
• Do not work alone or around explosive gas, vapor
or dust.
• Do not use the Tester in a damp or wet
environment.
• Examine the test leads for damaged insulation or
exposed metal. Check test lead continuity.
Replace damaged leads. Do not use the Tester if it
looks damaged.
• Be careful around voltages >30 V ac rms, 42 V ac
peak, or 60 V dc. Such voltages pose a shock
hazard.
• Keep fingers behind the finger guards on the
probes.
