fixture to the gold plated short circuit board (short circuit) or disconnect the outside of the fixture
(open circuit).

Step 2: Press the
key to carry out open or short circuit correction (automatic
identification of open circuit, short circuit, open circuit OPEN, short circuit SHORT) with the
interface as shown in Fig.4-18 (the number will be added 1 along with the correction progress,).
If the correction is successful, the word "success" is displayed in the position where "Digital" is
displayed. If it fails, "FAIL" will be displayed as shown in Fig.4-19; press the
key
again to return to Interface of Measurement Display.
