2.7.7 Between-Channel Error Test
1. Connect the Cal box to all channels in parallel.
2. Restore the initial balance values (all measuring ranges) of all channels to the
initial values from a PC via communication.
3. Enter the following settings.
Measurement range 2000 µSTR
Measurement Interval 200 ms
Filters OFF
Duration 10 s or more
Dip switch setting (for the -B12 and -B35 modules) 4-gauge method
ON

SW1 to SW4: OFF
SW5: ON
4. Apply the following input values and confirm that the between-channel error
satisfies the product specification.

For instructions on setting test points, see “Cal Box Settings.”
In the case of the -B12 and -B35 modules, since the between-channel error for all
channels will be equal to the wiring resistance error, be sure to make the wiring
resistance values the same.
