3 SAFETY INSTRUCTION
The instrument is not suitable using in outdoor especially in humid and dusty environment,
impropriate using may cause electronic shock. Before using the instrument, please read the safety
instruction completely in order to prevent any accident while using the instrument.
1. Security Signal
Caution
High voltage
Protect the GND terminal. Make sure the terminal connect the ground
conductor before using the instrument
Warning. Improper use of instrument may cause the instrument and DUT
breakdown
Warning. Improper use of instrument may caused injured or death
2. Electronic Shock
To avoid electronic shock, we strongly suggest to wearing rubber gloves before testing
3. Ground Conduction
Please make sure ground conductor at the back panel is well connected. Do not touch
the exterior case to avoid any accident
4. Power
The instrument built with 110V / 200V AC power. Please switch the AC power at the
back panel in order to match with the power which provide in the using area. Ensure
that only fuses with require type and current can be replaced, also please take off the
power before changing the fuses

6. Warm Up
Warm up the machine at least 15 minutes in order to make the testing value accurate.
The instrument can still work normally without any warm up
7. Exterior Control
Do not touch HV port and DUT during operation
8. Breakdown
Stop the operation and contact your agent or Microtest immediately while there’s abnormal
condition with the testers
9. End Up
Turn off the power when the tester is not in use and do not turn the power on and off
continuously
10. Placing
The instrument must be placed under temperature 5°C~40°C and humidity 80%RH.
Also, in order to make the instrument accurate and safe, please do not place the
instrument under sunshine, high temperature, high humidity, unstable and dusty places
11. Emergency
Turn off and power off if DUT or main instrument is burning
12. Generally Guide
(1) Do not put any inflammables or heavy articles above the instrument
(2) Do not let the instrument under any serious hit
(3) Do not turn on and plug in the power while cleaning the instrument
(4) Do not dismantle or fix the instrument while the instrument is under unusual circumstances
and contact your agent or Microtest Corp. directly
