HIPOT Tester 19051/19052/19053/19054 User’s Manual
<Formula>
Test Voltage * e
–t/RC
= Residual Voltage
Ex.: 1000V * e
–t/RC
= 30V
ln e
–t/RC
= ln 0.03
- t / RC = -3.5
t = 3.5 sec
10. Remote control the main unit
The instrument with remote control, high voltage output control by external control signal
usually. For your safety and prevent from hazard, please obeys the following rules.
• Don’t allow any unexpected high voltage output that may cause danger.
• When the main unit output high voltage, don’t permit the operator or others personnel
to contact DUT, test cable and probe output terminal.
11. Turn on or turn off power switch
Ú Note Ú
The product should be so positioned that the power switch can be easily reached by the
operator during emergency. When power switch is cut off, it needs a few seconds to
re-turn on. Please don’t turn on and turn off continuously. It is very danger to do that
under high voltage output. When turn on or turn off power, don’t connect any object to
high voltage output terminal to avoid hazard, which result from abnormal high voltage
output.
12. Others notice items
Don’t make short-circuited of output cable, grounding cable, transmission cable or AC
power to prevent from the tester is full of voltage. Please connect the cover of the tester
to earth firstly when high voltage output terminal is short-circuited with COMMON
terminal.
<<< Dangerous event >>>
13. The danger handling
Under any danger circumstances, such as shock, DUT burning or the main unit burning.
Please obey the following procedures to avoid the more danger.
y Cut off power switch firstly.
y Then pull off the plug of power cord.
<<< Solution >>>
14. Problems
Under the below circumstances, the occurred problem are very danger. Even press
[STOP] key, the output terminal may output high voltage.
y When press [STOP] key, DANGER indication LED is still light.
y The voltage meter without voltage reading but DANGER LED is still light.
When the above conditions are occurred, please turn off power and pull off AC power
plug immediately. Don’t use any more, please send to our company or office for
reparation.
15. DANGER indication LED error
When press [START] key, there is already reading on the voltage meter and DANGER
LED is still not light. In the meantime, the indication LED may be error please turn off
immediately. Please send it to our company or office for reparation.
16. If the tester needs long time using under normal operation. Please notice the
following items.
If the high limit setting value is 20.00mA (withstand voltage test), please notice its’
ambient temperature. When the ambient temperature is higher than 40°C, please stop
operation until it cools down to normal temperature.
