3.7.2 Parallel Operation
The front panel display on the master unit shows the total current for the units
connected in parallel.
The measurement accuracy can be improved by performing calibration in the
parallel configuration.
The setting resolution for parallel operation is different depending on the number of
instruments used.
Ammeter accuracy (RMS) : ± 2 % of FS
Ammeter accuracy (PEAK): ± 4 % of FS

Always keep the load wiring away as possible from the flat cable to prevent possible
unstable operation.
