3. It is recommended to connect the ta3000F analyzer and low powered
accessories to a dedicated electrical circuit. Do not plug the analyzer into
a circuit that is shared with other equipment with large intermittent cur-
rent loads. Line voltage spikes can have detrimental effects on the analyt-
ical capabilities. 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-
ing upon the size of the battery. Since the ta3000F
needs less than 5A of
current, the UPS battery pack can be relatively small.
Support Gas Utilities Preparations
The ta3000F needs support gases in order to run properly. Please refer to
Specifications, page 14 for detailed gas specifications for purchasing gases
in cylinders. In order to achieve the low detection limits, it may be essen-
tial to further clean the gases with external purifiers.
General Notes on Regulators and Plumbing
Ultra High Purity (UHP) regulators and gauges are suggested for all in-
coming gas streams
Use Cajon VCR fittings with gaskets to connect to UHP regulators. Do
not use pipe thread fittings since they are not clean and are not leak-tight
for trace gas analysis.
