For
SONDELTOX
detectors zeroing –except for
SONDELTOX
O
2
- please
proceed as follows:
1- Cover the detector during 15 min.
2.-Place a multimeter at the scale of 200mV, in parallel, with the yellow
and green cable (fig 1).
3- Adjust through the ZERO potentiometer of the detector circuit until a
reading of 40mV (4mA) is reached.
4- Remove the detector plug. With the plug provided and keep it for future
testings.
For
SONDELTOX
O
2
zeroing, adjust the potentiometer until obtaining a
measurement of 178mV, equivalent to 20.9% of O
2
, in a wide and well
ventilated room.
The detectors recalibration with gas must be carried out at our laboratories.
SONDELTOX has been tested with several commonly cross-interferring gases and the results are expressed in the table below (in ppm):
Use 2 x 1 mm
2
shield cable for power supply.
GREEN Cable:
Zeroing (multimeter positive borne)
YELLOW Cable:
Zeroing (multimeter negative borne)
BLACK Cable:
Negative of power supply. 4-20mA Output.
RED Cable:
Positive of power supply. 4-20mA Output.
SONDELTOX
CO is provided with a filter to minimize H2S influence, SO
2
and other interferring gases.
