Connect the output side of the AC adapter to the
connector indicated as "DC LINE" on the GL220.
Use a flathead screwdriver to push the button above the
ground terminal while connecting the grounding cable to the
GL220. Connect the other end of the cable to ground.

Shunt resistance
Ex: for current in the 4 to 20 mA
range, apply a resistance of 250 W
(±0.1%) and perform measurement
in the 1 to 5 V ra
nge.
Note: Use B-551 (option)
for this shunt resistance.
