Digital Meter Display: The meter display is a LED device that

It is accurate across all analysis ranges. The –TA models produce
continuous readout from 0-10,000 ppm and then switch to continuous
percent readout from 1-25 %.

Alphanumeric Interface Screen: The backlit VFD screen is an easy-

to-use interface between operator and analyzer. It displays values, options,
and messages that give the operator immediate feedback.

Standby Button: The Standby turns off the display and outputs,

but circuitry is still operating.

CAUTION: The power cable must be unplugged to fully

disconnect power from the instrument. When
chassis is exposed or when access door is open
and power cable is connected, use extra care to
avoid contact with live electrical circuits .
