5.2.8 Source and Measurement Timing

5.2.8.3

Integration Time and Measurement Time

The measurement time (Tm) is calculated from the integration time (Tit) and the internal processing time
(Tk) according to the following formula:

Tm = Tit + Tk

The integration time (Tit) can be selected between 100 

s to 200 ms.

The internal processing time (Tk) is determined by the source mode and memory store mode settings as
below.

When the memory store mode is OFF or Normal-ON, the following processing times are added by NULL
calculation, scaling calculation, Max/Min calculation, and comparator calculation.

NULL calculation ON:

Approx. 0.2 ms

Scaling calculation ON:

Approx. 1 ms

Max/Min calculation ON:

Approx. 1 ms

Comparator calculation ON:

Approx. 15 ms

In measuring resistance:

Approx. 1 ms

(Example) DC source mode, integration time: 1 PLC (50 Hz), memory store: Normal-ON, 

NULL calculation: ON, scaling calculation: ON, Max/Min calculation: ON,  
comparator calculation: ON
In these conditions, the measurement time is calculated as follows:
Tit = 20 ms
Tk = 4 + 0.2 + 1 + 1 + 15 = 21.2 ms
Tm = Tit + Tk = 41.2 ms
