Safety Precautions
3-5
14. Instrument Problems
The following is a very dangerous situation. If this condition occurs, turn off power and
remove the AC power plug immediately. Do not use the instrument; send it back to
Chroma for repair.
• If the DANGER LED does not go off when the [STOP] button is pressed, immediately
stop using the analyzer. It is possible that the output voltage is still being delivered
regardless of the TEST ON/OFF control signal.
15. DANGER LED error
When the [START] key is pressed, if there is already a reading on the voltage meter and
the DANGER LED is not illuminated, turn the analyzer off immediately. Return the unit to
Chroma ATE for repair.
16. Running the analyzer for an extended period of time.
Check the ambient temperature when running the ‘withstand voltage test’. If the high limit
setting value is 20.00mA, stop the test if the ambient temperature goes higher than 40°C,
and wait until it cools down to normal temperature before resuming the test.
17. Select the proper AC INPUT power setting.
Set the voltage selection switch on the rear panel to the correct position according to the
local power. Before plugging in the power cable, make sure the input AC power scale is
the same as the rear panel switch power setting. Make sure the proper fuse is installed.
See the following table for the correct voltage setting and fuse to be used:
Make sure the correct fuse/voltage combination is used. Replace the fuse only after the
power has been disconnected. Remove the fuse stand from the power socket and press
the new fuse into the fuse stand, then plug in the power socket.
Use the correct fuse when replacing the fuse. Failure to do so may
result in a hazardous situation.
18. Unstable AC power.
If the AC power is unstable within the selected voltage range it may cause the unit to
malfunction. If necessary, use a power stabilizer to correct the situation.
19. Analyzer drawing maximum current.
When the DUT is drawing maximum current before a fail judgment is made, it may
continue to draw the maximum current (about ten amperes) up to ten milliseconds before
shutdown.
20. Storage
The unit normally operates in a temperature/humidity range of 5°C ∼ 40°C, 80% RH.
Operating outside of this range may cause a malfunction. The unit storage
temperature/humidity range is -10°C ∼ 50°C, 80% RH. If the unit will not be used for a
long time, store it in the original packing material. Keep the unit from direct sunlight, high
temperature, vibration, humidity, or dusty places.
