Checkline TI-CMXDL - Manual (Page 3)

2.0 Q UICK -S TART G UIDE
Turn the TI-CMXDL on and off using the switch located on the bottom right corner of the key
pad. When TI-CMXDL is initially turned on, a flash logo and blinking lights are displayed. Th
the gauge attempts to identify the currently attached transducer (probe). The TI-CMXDL has a
“Auto Probe Recognition” feature that attempts to identify special transducers with feature bui
in . If the TI-CMXDL doesn’t find a transducer so equipped, the user must select a transducer
from the Probe Type list. The following sections outline each scenario.
NOTE: This section is primarily written as a basic startup guide only.
2.1 TI-CMXDL Overview
In order to understand how to operate the TI-CMXDL, it’s best to start off with an
understanding of what it is we’re looking at exactly. The TI-CMXDL has a lot of great
features and tools that will prove to be a huge benefit for the variety of applications you
constantly facing on a continual basis. Let’s have a brief look at the screens you’ll be
ºlooking at most often:
A. Repeatability/Stability Indicator – This indicator should be commonly used in con
junction with the digital thickness values displayed. When all the vertical bars are ful
illuminated and the last digit on the digital thickness value is stable, the TI-CMXDL
reliably measuring the same value 3 to 200 times per second, depending on which
measurement mode and features are enabled.
B. Battery Icon – Indicates the amount of battery life the TI-CMXDL has remaining.
C. Velocity – The material velocity value the TI-CMXDL is currently using or calibrated
Displayed in English or Metric units, depending on the what units the gauge is set for.
D. Feature Status Bar – Indicates the features currently enabled and in use in the
following order:
• Measurement Mode
• Differential Mode
• High Speed Scan Mode
• Alarm Mode
• Gain Setting
E. Digital Material Thickness Value – Extra large font size for viewing ease.
