Indicator LEDs and device tests
A minimum of 8 V is necessary to provide the correct power to the circuitry of the Hypertherm IGBT
tester.
IGBT test preparation
Do the following before you do a test with the Hypertherm IGBT tester:
 Connect the colored leads to the IGBT as shown on the next page.
 Electrically isolate the IGBT from all other circuits. If the IGBT is installed in a plasma power
supply, remove the power PCB and disconnect its lead connections before you do the
IGBT test.
The illustrations in Figure 4 on page 34 shows 3 common configurations of an IGBT. Each
connection on the IGBT has a label with an abbreviation. These label abbreviations can be C/E/G
or 1/ 2/ 3 with a schematic that shows numbers and pin functions.
Green “pass” LED
When illuminated, this LED indicates that the IGBT passed the test for an open circuit in the IGBT
when the switch is pressed to the right or for a short-circuited IGBT when the switch is pressed to
the left.
Red “fail” LED
When illuminated, this LED indicates that the IGBT failed the test for an open circuit in the IGBT
when the switch is pressed to the right or for a short-circuited IGBT when the switch is pressed to
the left.
Red “low battery” LED
When illuminated, this LED indicates that the remaining voltage in the battery is insufficient to power
the test circuitry. Replace the battery.
NOTICE
If you do not isolate the IGBT, you can get incorrect readings and cause damage to the IGBT tester.
