NOTE! Interrupting of sampling can not be done during a sampling sequence.
3.2 OVERFLOW PROTECTION
The sampler is provided with an overflow protection that protects the magnet valves and the compressor when
water is present in the vacuum tube.
When water is present in the vacuum tube the sampler immediately turns off all active functions and empties
the sample bottle.
Error code E-08 is shown on the display.
In this case, contact Elmacron AB.

3.3.1 INTERNAL
Internal control, number of samples / hour. Adjustable 1 - 36 samples / h.
3.3.2 PULSE
External pulse, which accumulates and compares pulses to a pre-set value (1 - 9999).
When accumulated value = pre-set value the sampler takes a sample.
External pulse (must be potential free) can be sent by a PC, flow meter etc.
(NOTE! See Specifications on page 15 for the pulse length accepted)
