Supplied Accessories:

[1] Measured at 100Hz, 1 Grms per ISA RP 37.2.
[2] Measure using zero-based straight line method, % of F.S. or any lesser range.
[3] Do not apply power to this system without current limiting, 20 mA MAX. To do so will destroy the IC charge amplifier.
[4] In the interest of constant product improvement, we reserve the right to change spec ifications without notice.
