Teledyne 2010A - Split architecture thermal conductivity analyzer - Manual (Page 13)

Part I 1- Teledyne Analytical Instruments
Thermal Conductivity Analyzer Part I: Control Unit
percent readout from 1-100 %. It is accurate across all analysis ranges.
Alphanumeric Interface Screen: The VDF 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.
Access Door: For access to the thermal conductivity sensor or the
front panel electronics, the front panel swings open when the latch in the
upper right corner of the panel is pressed all the way in with a narrow
gauge tool. Accessing the main electronics circuit board requires unfasten-
ing rear panel screws and sliding the electronics drawer out of the case.
(See chapter 5.)
1.6 Recognizing Difference Between LCD & VFD
LCD (Liquid Crystal Display) has GREEN background with BLACK
characters. VFD has DARK background with GREEN characters. In the
case of VFD (Vacuum Fluorescent Display) - NO CONTRAST ADJUST-
MENT IS NEEDED.
1.7 Equipment Interface (Rear Panel)
The rear panel, shown in Figure 1-2, contains the electrical connec-
tors for external input and output. The connectors are described briefly here
and in detail in chapter 3, Installation.
