Preliminary; During Use; After Use - Amprobe ACDC-400 Manual De Instrucciones

1.1. PRELIMINARY

• This apparatus has been designed for use in an environment of pollution degree 2.
• It can be used for CURRENT, VOLTAGE and FREQUENCY measurements on
installations of surge voltage category III up to 600 V, voltage between Phase and
Earth (fixed installations) and for current measures up to 400A.
• This meter is not available for non-sine wave AC signals.
• You must comply with the usual safety regulations aimed at:
♦
Protecting you against the dangerous electric current.
♦
Protecting the instrument against an incorrect operation.
• Only the leads supplied with the instrument guarantee compliance with the safety
standard. They must be in a good condition and they must be replaced, if necessary
with an identical model.
• Do not test or connect to any circuit with voltage or current exceeding the specified
overload protection.
• Do not perform any test with environmental condition exceeding the limits indicated in
paragraphs 6.2.1.
• Check if the batteries are installed correctly.
• Prior to connecting the test probes to the installation, check that the function selector is
positioned on the required measurement.
• Check if the LCD and the range indicator show the same as the function desired.

1.2. DURING USE

Read the recommendations that follow and the instructions in this manual:
Non compliance with the warnings and/or the instructions for use may
damage the apparatus and/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
terminals.
• 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

• Once the measurements are completed, turn the rotary switch to OFF.
• If you expect not to use the instrument for a long period of time remove the batteries.
