Precautions Before Use; Electrification And Electric Shock; Ground; Power - Microtest 7630 User Manual

1. Precautions before use

This tester outputs voltage as high as 5kVac/6kVdc for external testing; accidents will happen if this
tester is used incorrectly or improperly. Therefore, in consideration of your own safety, please read
the precautions described in this chapter carefully and memorize them in order to prevent accidents
from occurring.

1.1 Electrification and Electric Shock

In order to prevent electric shocks, the wearing of insulating plastic gloves is recommended
before using this tester to perform testing related tasks.

1.2 Ground

This is a safety ground terminal on the rear panel case of this tester. Please ground this
terminal properly in order to prevent electric shock accidents from occurring when touching
the case.

1.3 Power

Power that can be used with this machine is AC 100Vac~240Vac with a frequency range
from 47Hz~63Hz; please confirm whether the input power voltage and frequency are within
range before inserting the power.

1.4 Connect the testing cable to the high voltage output terminal

While the tester is powered off, insert the high voltage testing cables to the high voltage
output terminals on the tester respectively, and confirm that the exteriors of the testing
cables are not ruptured or shed.

1.5 Warm up

The tester can operate normally once the power is turned on; however, in order to achieve
the accuracy within specification, please turn on the machine in advance and let it warm up
for 15 minutes or more before use.

1.6 External control host

This tester can perform external control; make sure the operator is not touching the high
voltage output terminal and DUT when performing such controls in order to avoid causing
danger.

1.7 Machine malfunction

If it is discovered that this tester has malfunctioned, for example: the voltage displayed on
the voltmeter differs greatly from the voltage set, or there is no high voltage output but the
high voltage output warning indicator remains on etc., cease usage immediately and contact
our company or your dealer to perform repairs.

1.8 Test End

Turn off the power switch when the tester is not being used.

1.9 Placement and Storage

The normal temperature and humidity range of this machine is 5
actions might be abnormal if exceeding this range. The storage temperature and humidity
range of this machine is -20
safety considerations, do not place this machine in environments with direct sunlight
exposure, high temperature, high humidity, frequent vibrations or excessive dust.

1.10 Emergency Measures

When there is an electric shock or if the DUT or machine catches on fire, please switch
off the power and unplug the power cable.
