A.1 GENERAL SPECIFICATIONS
(These specifications apply equally to all 3500 Series models.)
Physical: DIN package outline of extruded metal, with splash-resistant front
panel; secure rear connections via screw terminals. Instrument weight approx-
imately 3.25 lb (1.47 kg). For dimensions, see Fig. 25, below.
Power Requirements:
Input Voltage Range: 90-265 V-AC
Frequency Range: 50-400 Hz
Power In (Max): 10 W
Environmental:
ESD Immunity: Meets Class 3 Industrial Standard (8 kV) everywhere on the
case and on every line
Operating Temperature Range: 0° C to +50° C (+32° F to +122° F)
Storage Temperature Range: -40° C to +80° C (-40° F to +176° F)
Operating Humidity Range: 10 to 95% max, noncondensing
Display: 5-digit LCD reflective, non-light-emitting
A/D Conversion: 16-bit; approximately 1-kHz conversion rate; transparent auto-
calibration every 2 seconds
Digital Filtering selectable from front panel
Limits: Three limit zones ("HI," "OK," "LO") with front-panel annunciation and cor-
responding TTL-level logic outputs (outputs for HIGH and LOW limit conditions
can be latching or nonlatching). Each limit setpoint has a user-settable hys-
teresis window to prevent toggling of the limit output from signal noise.
Serial Communications: 9-pin RS-232/RS-485 Port (interface mode selectable
by node-number setting); standard baud rates up to 153.6K for both RS-232
