Precautions on Handling
This chapter describes the precautions to be followed in the handling of this tester.
When using the tester, take utmost care to ensure safety.
• The tester derivers a 5 kVAC/6 kVDC test voltage which can cause human
injury or death. When operating the tester, be extremely careful and
observe the cautions, warnings, and other instructions given in this chap-
ter.
2.1 Prohibited Operations
■
Do not turn on/off the po wer repeatedl y
After turning OFF the po wer switch, be sure to allo w se v eral seconds or more
before turning it ON ag ain. Do not repeat turning ON/OFF the po wer switch rapidly
–if you do this, the protectors of the tester may not be able to render their protecti v e
functions properly . Do not turn OFF the po wer switch when the tester is deli v ering
its test v oltage–you may do this only in case of emer genc y .
■
Do not shor t the output to the ear th gr ound
P ay attention so that the high test v oltage line is not shorted to a nearby A C line or
nearby de vices (such as con v e yors) which are connected to an earth ground. If it is
shorted, the tester chassis can be char ged up to the hazardous high v oltage.
Be sure to connect the protecti v e grounding terminal of the tester to an earth line. If
this has been securely done, e v en when the HIGH V OL T A GE terminal is shorted to
the LO W terminal, the tester will not be damaged and its chassis will not be char ged
up to the high v oltage.
Be sure to use a dedicated tool when grounding the protecti v e grounding terminal.
See " • This product is an IEC Safety Class I equipment (equipment with a protec -
ti v e conductor terminal). T o pre v ent electric shock, be sure to ground (earth) the
unit. " .
• The term "A C line" here means the line on which the tester is operating. That is
the line to whose outlet the A C po wer cable of the tester is connected. It may be of
a commercial A C po wer line or of a pri v ate-generator A C po wer line.
■
Do not appl y an External V olta ge
Do not apply a v oltage from an y e xternal de vice to the output terminals of the tester .
The analog v oltmeter on the front panel cannot be used as stand-alone v oltmeter .
The y may be damaged if their output terminals are subject to an e xternal v oltage.
