3. Repeat the procedure for the remainder of the ranges
(5.0mA~20A).
Note: Ensure the correct terminal is used for each
range.

*Do not input 19A for more than 1 second. Exceeding 1
second may blow the fuse.
Calibration
procedure
1. Set the range to 500uA (ACA) on the GDM-8245.
2. Input 490uA/20Hz. Verify 490uA(20Hz)<378
