OP TION A L VERSION S
Optional versions have identical specifications and accessories as listed for the standard model except
where noted below. More than one option may be used.
N OTES:
[1]Low frequency response specified into 1M ohm load.
[2]Excitation voltage to sensor limited by optional DC power voltage.
[3]With 1M ohm load.
[4]Un-buffered output, read out device input impedance affects discharge time constant and low
frequency response of unit.
[5]Alkaline type recommended for longest service life.
[6]Use BNC's or Triax connector, not both at once. Cover all unused connectors with black ESD
protective caps.
[7]See PCB Declaration of Conformance PS024 for details.
