Between 1 – 2 : CH4 span calibration contact
output
Between 3 – 4 : CH3 span calibration contact
output
Between 5 – 6 : CH2 span calibration contact

Between 7 – 8 : CH1 span calibration contact
output
Between 9 – 10 : Zero calibration contact output
When the calibration contact
output is measured with manual
calibration, the calibration
contact corresponding to cali-
bration channel is conductive.
For the automatic calibration,
they are worked sequentially
according to “6.4 Auto calibra-
tion setting”. If calibration is
not performed, all of them are
open.
Between 11– 12 : For internal connection. Must
not be wired. (Must not be used
as junction terminal.)
Between 13– 14 : Automatic calibration in
progress, contact output. Con-
ductive during automatic
calibration. Open otherwise.
Between 15– 16 : Calibration error contact output.
Conductive when error is
produced at zero or span calibra-
tion. Normally open.
Between 17– 18 : Pump ON/OFF contact output.
(Used for turning ON/OFF the
pump. Conductive during
measurement and open at zero
span calibration.)
Note: For the output of calibration contacts, see
Item 3.5 (9) “Timing of calibration
contact output”.
