Chapter 1 Unpacking and Installing
This chapter tells some of the check points that must be performed after you receive the instrument
and things you must know before installing the instrument.
1.1
Precautions for Use
Be sure to follow the rules below when using the instrument:
Do not use the instrument in flammable air
To prevent burning or explosion, do not use the instrument near alcohol, thinner and other
flammable materials, or in air with high concentrations of these gases.
Avoid exposing the instrument to high temperatures and direct sunlight
Do not place the instrument where it is hot or where the temperature changes drastically.
Operating temperature range:
5
℃
to +35
℃
Storage temperature range: -20
℃
to +60
℃
Avoid wet environment
Do not place the instrument in a boiler, humidifier or high humidity environment with water.
Operating humidity range:
20% to 80%RH
(dew condensation is not allowed)
Storage humidity range:
<90%RH
(dew condensation is not allowed)
Water condensation can cause the circuit to malfunction. The instrument can only be used when the
environment is completely dry.
Do not place the instrument in an environment with corrosive gas or dust
Do not use the instrument in an environment where corrosive gases such as sulfuric acid, fog, dirt
and dust or the like are present. This can corrode wires, connectors, and create hidden dangers or
connection defects that can cause malfunctions, failures, and even fires.
Do not use the instrument in a poorly ventilated area
The instrument has a forced air cooling system. Please allow enough space for the side and rear air
vents to ensure air circulation.
Do not use the instrument on a sloping surface or in a rocking place
If the instrument is placed on a non-horizontal surface or shaken, the instrument may slip and
damage the instrument.
Do not use the instrument where there is a strong magnetic field or electric field effect
Use the instrument where there is a strong magnetic field or electric field. Electromagnetic pulses
can cause a malfunction in the instrument.
Do not use the instrument near sensitive measuring instrument or receiver
Operation in a location subject, may cause such equipment be affected by noise generated by the tester.
At a test voltage exceeding 3 kV, corona discharge may be generated to produce substantial amounts
of RF broadband emissions between grips on the test lead wire. To minimize this effect, secure a
sufficient distance between alligator clips. In addition, keep the alligator clips and test lead wire away
from the surfaces of conductors (particularly sharp metal ends).
1.2
Precautions when moving
When moving or transporting the instrument, be aware of the following precautions:
Turn off the power switch before moving
Moving with the power switch on will cause electric shock and damage.
