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]For +10 volt output, minimum 26 VDC supply voltage required. Negative 10 volt output may be
limited by output bias.
[2]Two identically spec'd elements spaced 10cm apart - see drawing #65310 for details. Individual
calibration certs supplied for each channel.
[3]Typical.
