10.6

Problems with the totalizers

The values of the totalizers are too high.

• See

Special Funct.\SYSTEM settings\Measuring\Quantity recall

. If this menu item is activated, the

values of the totalizers will be stored. The totalizers will continue with these values when starting the next measurement.

The values of the totalizers are too small.

• One of the totalizers has reached the upper limit and has to be reset to zero manually.

The sum of the totalizers is not correct.

• See

Special Funct.\SYSTEM settings\Measuring\Quant. wrapping

. The sum of both totalizers

(throughput) transmitted via an output is no longer valid after the first overflow (wrapping) of one of the totalizers.
