4.1.2 External control
External controlled sampling is performed after pre-setting of the parameters that effects the sampling
frequency.
External control device is connected through the Amphenol-contact at the lower side of the sampler.
A. Flow control sampling
Samples are taken in proportion to the flow; the sampler gets a signal from a flow meter.

.
NOTE! Control that the interval < max flow, and that max flow / interval not exceeds 36 samples/h.
12. The sampler steps automatically to
MAN SAMPLE
.
13. Step to
ANALOG
with
M
.
14. Set the signal range (0 - 20 mA alt. 4 - 20 mA) with

(the display shows the actual flow in % of max flow).
Example of settings at flow controlled sampling
Ex.1
Max. flow
5,5 m
3
/h
Interval 2
m
3
between samples
The sampler takes samples according to 5,5/2 = 2,75 samples/h, one sample every 22nd minute at max. flow.
Ex.2
Max. flow
3,6 m
3
/h
Number of samples 3 samples/h
