4.3.1
Installation of Coaxial Cable to Guard Terminal XE1
CAUTION!
Maximum length of the coaxial cable 10 m
Incorrect measured value due to too long a coaxial cable
Possible consequence: Slight or minor injuries. Material damage.
The maximum length of the coaxial cable may not exceed 10 m when using redox or
pH sensors. The measurement signal can otherwise be falsified by the effects of
interference.
If the distance between the pH/ORP measuring point and the DULCOMETER
is more than 10 m, the use of a DULCOTEST
V1, rH V1 is recommended. Connection is then via terminal XE4 of the
DULCOMETER
®
The XE4 (mA input) terminal is an auxiliary function that incurs an extra charge.
When installing the coaxial cable for the guard terminal XE 1, the allowances shown in
the diagram Fig. 18 for stripping insulation from the coaxial cable must be adhered to.
The guard terminal should be tightened until "hand-tight".
