Product Notes
[1] Low frequency response specified into 1M ohm load.
[2] Alkaline type recommended for longest service life.
[3] With 1M ohm load.
[4] Excitation voltage to sensor limited by optional DC power voltage.
[5] Un-buffered output, read out device input impedance affects discharge time constant and low frequency response of unit.
[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.
