is essential in order to keep constant pressure and flow rate. Always keep
gas containers inside the building where temperature fluctuations are at a
minimum.

block any vent slots in the rear or top of the analyzer since limited air
circulation will cause overheating and poor performance.

Electrical Preparations and Connections

1. Always verify that the voltage on the label located on the rear of the
instrument matches the supplied power before connecting. The electri-
cal requirements for the Reduction Gas Analyzer can be 100, 115, 220, or
240 VAC, and 50 or 60 Hz, depending on the voltage option ordered. AC
power must be free from cyclic RMS voltage variations, spikes or drops
greater than 1.5%. A minimum of 5 amperes current must be available.
2. Good grounding of the AC power circuit is required, verify proper
receptacle grounding before connecting the instrument.
3. It is recommended to connect the analyzer and low powered accesso-
ries to a dedicated electrical circuit. Do not plug the analyzer into a circuit
that is shared with other equipment with large intermittent current loads.
Line voltage spikes can have detrimental effects on the analytical capabili-
ties. Where there are noisy circuits, a power line conditioner should be
considered to even out spikes and other fluctuations.
4. Frequent power failures in the area where the analyzer is used are best
taken care of by installing an uninterruptible power supply (UPS). The
UPS will supply power instantly from batteries when the main power is
interrupted. Proper power will be supplied for minutes or hours depend-
