The facility must be designed (configuration of the voltage and the load resistances) so that
the cycle ratio

almost achieves the value 1 upon attaining the maximum load resistance

(e.g. due to ageing at the end of the life-cycle or due to achieving operational
temperature).
7.3 Additional Measurement Device
The Thyro Power Manager can also be deployed as additional measurement device (ZME).
In the course, the Thyro Power Manager substitutes the ZME cards as used up to now. If
electrical currents are measured using common measurement instruments upon deployment
of full frequency package control (TAKT), a significantly fuzzy display results. This does not
occur if using the Thyro Power Manager.
The Thyro Power Manager possesses three AC measurement inputs, which are designed for
the connection of electrical current or voltage converters (see also chapter 4.5.4.3 page 19
for more). Principally, alternating voltages ranging from 0 – 1V~ may be measured using
these three inputs (see also chapter 4.5.4.8 page 24 for more). The time measurement
interval and the integration time for measurement can be adjusted (standard value = T0 = 1s,
Poti R309).
