STM-2XM Operating Manual

Test Mode . . . . . . . . . . . . . . . . . . . . . Test mode provides simulated sensor

readings.

NOTE: If STM-2XM is reset, test mode is

turned off automatically.

Active Source
(Active Channel) . . . . . . . . . . . . . . . . For single film modes, this selects where the

analog and digital outputs and inputs are
connected (refer to

Display Mode. . . . . . . . . . . . . . . . . . . Displays thickness in kiloangstoms (kÅ) or

mass in micrograms per square centimeter
(µg/cm

Plot type. . . . . . . . . . . . . . . . . . . . . . . Available in single film modes.

Displays the graph on the Runtime screen as
None, Rate Deviation, Rate, or Thickness.

Plot time scale. . . . . . . . . . . . . . . . . . Sets the horizontal axis size. Defines the

amount of time covered by the plot before it is
overwritten.

LCD Contrast
LCD Brightness. . . . . . . . . . . . . . . . . Adjusts the appearance of the screen. Set the

brightness to 100%, and then adjust the
contrast until the display is easily read.
Brightness can be programmed to a desired
level.

NOTE: The screen dims when STM-2XM is

idle.

Beep [on/off] . . . . . . . . . . . . . . . . . . . Turns the button/control knob beeper on or off.

Comm Protocol . . . . . . . . . . . . . . . . . Serial communications mode to STM-2XM,

Sycon 9600 (9.6 Kbps), SMDP L (9.6 Kbps),
SMDP M (38.4 Kbps), and SMDP H (115.2
Kbps).

If the protocol selected is Sycon 9600,
STM-2XM performs serial communication with
Sycon protocol at 9600 baud, using RS-232
electrical levels.

If the protocol selected is SMDP, STM-2XM
performs serial communication using SMDP
protocol at 9600, 38400, or 115200 baud.
