CAUTION
In such cases, an overload situation on a single load cell cannot be detected from the out­
put signal.
Cable extension
For extending cables, only use shielded low capacity measurement cables (measurement
cables provided by HBK
1)
meet these requirements). Ensure that there is a perfect con­
nection with the lowest possible transition resistance. If you use the 6‐wire circuit, you
may neglect any interference by a change in the resistance of the extension cables. How­
ever, if you extend the cable in a 4‐wire circuit, the characteristic value deviation may be
removed by adjustment. Temperature influences will be compensated only in 6‐wire cir­
cuits.
Connector pin assignment for option with M12 male connector
Plug-in contact 1 = measurement signal (+)
Plug-in contact 2 = not in use
Plug-in contact 3 = sense lead (+)
Plug-in contact 4 = not in use
Plug-in contact 5 = sense lead (-)
Plug-in contact 6 = excitation voltage (-)
Plug-in contact 7 = excitation voltage (+)
Plug-in contact 8 = measurement signal (-)

e.g. HBK‐extension cable, 6 wires:
- KAB8/00‐2/2/2 (sold by the meter, order no. 4‐3301.0071 = grey or 4‐3301.0082 = blue)
- CABA1 (cable reel, order no. CABA1/20 = 20 m or CABA1/100 = 100 m in length)
