TM-1016
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:
WAR WARNING NING
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.
