NSTRUMENTS
The TMA display is the lighted area of the
keypad unit (see Figure 1.2). It contains two
rows of 20 characters each.
During normal operation, the display is divided
into three areas:
• Method status display—the eight-character
line on the top left
• Sample temperature display—the nine
characters on top right
• Realtime signal display—the whole bottom
line.
The instrument keypad (Figure 1.2) contains the
keys found in Table 1.1 on the next page and the
HEATER and POWER switches.
Experiment and instrument constants are entered
from the controller keyboard, not the instrument
keypad.
