13. Problems occurred
Problems occurred in the following situation are very dangerous. The output terminal
may still have high voltage output even the STOP key is pressed; therefore, users should
be extremely careful when dealing with it.
․ The DANGER LED indicator keeps on when STOP key is pressed.
․ The DANGER LED indicator is on but the voltage meter has no readings.
When the above situation occurs, shut down the power and unplug the AC power cord
immediately. Do not use the device again as failure is awfully hazardous. Please send
the hardware back to Chroma or its distributor for repair service.
14. DANGER Indicator failure
When pressing the START key the voltage meter has readings but the DANGER LED
indicator is still off, it means the indicator may be broken. Please power off the hardware
and replace it with another device, then send the broken one back to Chroma or its
distributor for repair service.
15. Tester uses 110Vac / 220Vac, 50 / 60 Hz for AC INPUT
The fuse should be changed when the power cord is not plugged in to avoid electric
shock. When replacing, use a flat screwdriver to pry the fuse holder inside the power
socket and remove the fuse to replace with a new one by pushing it in gently, and then
push the power socket back to its position.
Be sure to use the fuse with correct specification or it may cause hazard.
16. Tester is normally operated under AC power
Unstable power supply may cause the device to work inaccurately or abnormally. Thus,
please use appropriate equipment such as a power supply regulator to convert it to a
suitable one.
17. Storage
The temperature and humidity for the Tester is 0°C~40°C, 10%~90% RH in normal. The
operation may malfunction if exceeding the range. Do not mount the Tester to a fixed
place in case it needs to be removed. The storage temperature for the Tester is from -0°C
to 50°C, ≤ 90%RH. If it is not in use for a long time, please pack it with its original
package for storage. For proper test and safety measures, do not place the Tester under
direct sunlight, high temperature, vibrated, humid or dusty area.
18. Warming up
The tester is activated when power is on; however, in order to meet the specifications for
accuracy please warm it up for 30 minutes or above.
19. Keep test cable away from the panel
Please keep the high voltage cable or the DUT away from the panel at least 15 cm during
operation to avoid the display interference caused by high-voltage discharge.
20. Notices for connecting automated device
• The grounding system of the device and the automated station should be connected
together.
• The high voltage cable must be separate from the control cable.
• The high voltage cable must keep proper distance from the Tester panel.
