Wiring for bridge voltage accuracy test (with -B12 and -B35)
Dip switch settings: 4-gauge method
ON

SW1 to SW4: OFF
SW5: ON
Wiring Diagram (Ex.: CH2)
Because the bridge voltage accuracy error will be equal the wiring resistance from the
clamp terminal to the load resistance, the effects of wiring resistance must be kept to
0.5% or less.
