Features：
1 Connection terminal
Current output “I+、I-” connected to outside end of trial product's resistance；
“V1+、V1-”namely voltage input terminals of channel 1 and “V2+、V2-”namely voltage input terminals of channel 2。 2 Earthing terminal: protecting the unit.
3 Temperature probe plug end.
4 Arc suppression：can do indication of Arc status, in addition, it is no caution for small transformer with direct Arc inside.
5 Power socket：AC 230V±10%（with 10A safe fuse inside）.
6 Power switch.
7 Contrast knob：used to adjust contrast.
8 USB jack.
9 Keypress “left key、right key、INTER”: used to adjust cursor position and numerical value and then confirm.
10 LCD screen.
11 Printer：printing test data.
Note：
1 Ensure reliable earthing and turn on the unit after finishing connection; to avoid possible accident, don’t move the test lead during test of output current; when finishing the test, you 2 can turn off after Arc indication alarm stops, then move the test lead.
3 When testing no-load-tap power transformer, please don’t switch tap point and range until discharge indication alarm stops.
4 To avoid electromagnetism disturb to get better test, please make short circuit for windings which don’t need test.
5 When automaticlly testing, the unit will output maximum current according trial product’s resistance; when by manual, please choose possible maximum current to improve test accuracy.
6 During test, the user can choose channel, resistance value of selected channel will be displayed.
