If you have a warranty claim, return the cell in question to the
factory for evaluation. If it is determined that failure is due to faulty
workmanship or material, the cell will be replaced at no cost to you.
WARNING: EVIDENCE OF DAMAGE DUE TO TAMPERING OR
MISHANDLING WILL RENDER THE CELL
WARRANTY NULL AND VOID.
The Model 3110 is designed to meet Factory Mutual standards for
intrinsically safe for Class I, Division I, Groups A, B, C and D
hazardous locations. (Approval pending at time of manual printing.)
This safety feature does not apply when the instrument is being
charged with the 100- 240 VAC external charge adapter. The instrument
should be removed from hazardous areas when the batteries are being
charged.
Note: Do not use the analyzer when the battery charge is low.
1.5 Accuracy and Response
The Model 3110 provides monitoring accuracies of ±2% of full
scale or ±1 ppm, whichever is greater, at constant temperature.
With a sample flow rate of 1 SCFH, a 90% response can be realized
in 60 seconds. The response time on the 3110 is limited by the filter
setting.
1.6 Signal Output
The standard 0-1 VDC output has a 100 ohm impedance and is
suitable for driving external devices that have an input impedance of
10,000 Ω or more. The signal output is available from a port on the rear
panel.
1.7 Compact Packaging
The instrument is housed in 6 1/8" Ч 9 ½" Ч 5 5/8" (156 Ч 241 Ч
143 mm) aluminum case that is equipped with a carrying handle and
foot pads. Unlike analog instruments where uneven positioning may
