45 series 145 series logic device test (the need to manually enter the model) |
|
OTHER |
Interface drive device testing, such as: MAX232, MAX485, 75175, 75176, 75c11.. (the need to manually select the model) |
|
AMP |
Operational amplifier, comparator class testing, such as: LM324, LM358, LM339, LM393, LM2902...(the need to manually enter the model). |
|
TR |
Transistor identification , and automatically determine the transistor |
|
ZD |
Zener regulator value test , test regulator regulator 0v-50v range accuracy 0.01v automatic identification without the need to enter |
|
LIGHT |
Optocoupler secondary the saturation voltage test , can test the the ordinary 4 feet optocoupler secondary |
|

Shutdown |
The panel has 5 buttons are on the left, right, bottom, and Enter keys.
The next key is used to adjust the directory and change the model number, the or so key to move around the cursor options to change.The Enter key for the switch machine and execute the test command.Gently open the battery cover, add a 2X1.5V laminated battery, and then close the battery cover.Press Enter for more than 2 seconds can boot, boot automatically display the current battery voltage, when the voltage is lower than 2.5V, please replace the battery, the low voltage will affect the reliability of the test result and protection automatic shutdown.
Boot: Enter key press 2 seconds then boot.
Shutdown: 1 in the OFF directory, press Enter button to immediately shutdown.
2 in any directory, press Enter button for more than 10 seconds then off.
3 in no operation after 60 seconds, automatic shutdown
ethods of devices placed:
1, the top of the chip alignment
2, put the most left transistor three slot
3, a 13 foot alignment IC Optocoupler
4, voltage regulator tubes placed IC block 13 and 14 feet.
Note: the transistor display pin order from left to right and the corresponding IC block, 10 feet, 11 feet, 12 feet
