ACD-55HPQ
• Only the leads supplied with the instrument guarantee compliance with the safety
standards. They must be in good condition and, if necessary, be replaced with identical
leads.
• Do not test circuits exceeding the current and voltage limits.
• Do not perform any test under environmental conditions exceeding the limits indicated
in paragraphs 6.2.1.
• Assure the batteries are installed correctly.
• Before connecting the test leads to the circuit to be tested, make sure that the rotary
selector switch is set to the correct function.
• Make sure that the LCD and rotary selector switch indicate the same function.
1.2. DURING USE
WARNING
Non compliance with warnings and/or instructions may cause damage to
the tester or its components or injure the operator.
• Remove the clamp jaw from the conductor or circuit under test before changing the
range.
• When the tester is connected to the measuring circuits, do not touch any unused
terminal.
• Do not measure resistance in the presence of external voltages. Even if the circuit is
protected, excessive voltage could cause the instrument to malfunction.
• When measuring current with the clamp jaws, first remove the test leads from the
instrument’s input jacks.
• When measuring current, any other source near the clamp jaw could affect its
accuracy.
• When measuring current, always put the conductor to be tested in the middle of the
clamp jaw to obtain the most accurate reading as referred into paragraph 4.1.2.
• While measuring, if the value remains unchanged check if the HOLD function is
enabled.
1.3. AFTER USE
• After taking measurements turn off the clamp.
• If you expect not to use the instrument for a long period of time remove the batteries.
