GENERAL
This chapter provides operating instructions for most features of the Model
CYD211 Temperature Monitor. Corresponding computer interface
instructions for these features are provided in Chapter 4.
3.1
INSTRUMENT POWER
The Model CYD211 is powered on by plugging in the power supply. There
is no power switch on the instrument. When the Model CYD211 is powered
on every segment on the display will illuminate for a few seconds to
indicate instrument initialization. Most of the instrument setup parameter
values are retained when powered off with one exception. The latching
alarm will reset itself on power-up. When the instrument is powered on for
the first time parameter values are set to their defaults, listed in Table 3-6.
When initialization is complete the instrument will begin its normal reading
cycle and temperature or sensor units readings should appear on the display.
Messages will appear in the reading location on the display if the
measurement input has not been fully configured. Messages listed in
Paragraph 5.3.1, Instrument Hardware Errors, are related to the instrument
hardware and may require help from Omega service. The messages listed in
Paragraph 5.3.2, Limit Errors, do not indicate a problem with the instrument
and will disappear when input setup is complete.
The Model CYD211 should be allowed to warm up for a minimum of 30
minutes to achieve rated accuracy.
3.2
DISPLAY DEFINITION
The Model CYD211 has a 6-digit LED display capable of showing both
numeric and character data. In normal operation the display shows the
current sensor reading in sensor units or temperature units. The four
annunciators below the right hand side of the display indicate what units the
display is reading in. Other display configurations appear during parameter
setting and data entry operations. These displays are illustrated in their
individual operation paragraphs.
