Extension Cables
The clamp-on sensors are equipped with a 2-m cable for connec-
tion to the meter, but an extension cable can be inserted if neces-
sary. Available extension cable lengths are 5, 10, 20, 30, 50 and
100 m.
Model 9691 + extension cable + Model 3290-10 MON output frequency
characteristics
Appendix
• Note that a long cable may result in a larger value being dis-
played when no or low input is made due to noise.
• When using an extension cable, note that the accuracy will be
within the specifications, but the frequency characteristic may
vary. Moreover, the longer the extension cable, the greater the
variation in accuracy.
The graph below shows frequency characteristic differences
among standard equipment, that with a 10 m extension cable,
and that with a 100 m extension cable.
