A current limiting resistor (R1 and R2) is potted into the end of each battery. This assures that under no circumstances can more than 25 milliamperes (100 milliwatts) be switched or drawn from either battery supply. This means that the Model 311XL may be used in explosive atmospheres where arcs of 100 milliwatts or less can be tolerated.

This safety feature does not apply when the instrument is being charged (AC power cord connected and selector switch in the “OFF” position). The instrument should not be used in explosive atmospheres when the batteries are being charged.

To determine the state of the rechargeable batteries turn the range selector knob counterclockwise to the battery test position and hold there (spring loaded switch). Observe that the meter indicator stays within the battery limits, *if not, recharge of the batteries is in order). Release Range Selector Switch, it will automatically return to the OFF position.

1.3.4Accuracy and Response. Accuracy at 25oC and constant pressure after thermal equilibrium has been reached. Basic accuracy: +/- 2% of full scale for all ranges except 0-2 PPM range. Accuracy for 0-2 PPM range: +/- 5% of full scale.

Accuracy over the temperature range 0-35oC at constant pressure after thermal equilibrium has been reached. Basic accuracy: +/- 5% of scale for all ranges except 0-2 PPM range. Accuracy for 0-2PPM range, +/- 10% of full scale.

If the instrument is moved from one ambient temperature to another of 10oC or higher differential, the instrument should be allowed to equilibrate for 3-4 hours before being used. The readings obtained during the transition time may be in error greater than the specifications.

Response time: 90% in 90 sec. on the 0-2 PPM range with a flow rate of 2.5 SCFH.

1.3.5Compact Packaging. The instrument is housed in a 6-1/8” X 9-1/2” X 5- 5/8” aluminum case that is equipped with a carrying handle and foot pads. When in use, the analyzer should be placed in an upright position on a level surface (off level positioning will detract from meter accuracy).

Access to the instrument interior is gained by loosening (ccw) the three (3) 1/4 turn screw driver type fasteners on the back of the outer case. The case may then be detached from the driver type fasteners on the back of the outer case. The case may then be detached from the control panel assembly. Further disassembly may be accomplished by removing the back plate assembly from its four (4) mounting standoffs and laying the two separated assemblies out as illustrated on the “Analyzer Wiring Diagram”. The diagram is included among the drawings at the rear of the manual.
