Checkline TI-CMXDL - Manual (Page 4)

F. Scan Bar – Another view of material thickness in a deflection style horizontal bar. This
visual tool enables the user the ability to see thickness changes during high speed scans
from flaws and pits.
G. Units – The current measurement units being used (English, Metric).
H. Digital Material Thickness Value – Smaller font size when the B-Scan display
view is enabled.
I. Coating Thickness Value – Displays the actual thickness of any coating adhered
to a metallic material surface (PECT Mode), or a coating adhered to a non-metallic
surface (CT Mode).
J. Minimum Material Thickness – Part of the Alarm feature. Displays the minimum
thickness value found during a scan.
K. Maximum Material Thickness – Part of the Alarm feature. Displays the maximum
thickness value found during a scan.
L. B-Scan Display – Cross section view of the material. Provides the user with graphical
view of the opposite/blind surface (i.e. inside pipe wall surface), to give the user some
idea of the condition, or integrity of the material being tested.
2.2 Auto Probe Recognition
When the TI-CMXDL is initially powered up, the gauge will automatically check to see if
the transducer plugged into the gauge can be recognized. The steps that follow assume the
TI-CMXDL recognized the probe type:
1. Press the OK key once to use the identified probe,
or ESC to display a list of optional transducers.
NOTE: If the TI-CMXDL recognizes a specific
transducer, the user should always select OK
to use the identified probe. The only time an
alternative probe should be selected from a list
is if the user switched probes following initial
power up and recognition.
2. Assuming the TI-CMXDL recognized the probe and
the OK key was pressed, the TI-CMXDL will
advance to a Zero Probe menu. If the transducer was
identified as a special transducer capable of measuring
coating thickness, a menu will be displayed allowing
the user the ability to toggle the coating thickness
display on/off as follows:
3. Press the UP and DOWN arrow keys to toggle the
coating option on/off.
4. Wipe all couplant from the transducer face
and advance to the Probe Zero & Calibration
section, 6.0.

14.0 L OW B ATTERY I NDICATOR & C HANGING THE B ATTERIES
The TI-CMXDL has a Battery Strength Indicator (illustrated here) that
provides the user with information about the remaining strength of the
batteries. There are 11 steps from 100% (full) to 0% (empty). As the
battery voltage drops, the number of pixels that are dark will be reduced.
When the battery outline is nearly empty, we suggest changing the
bateries. Any type of AA size battery can be used including alkaline
(1 time use) or rechargeable.
There is no re-charging function provided with this gauge, so
rechargeable batteries will have to be recharged externally. Please
note that alkaline batteries will provide a longer run time then most
rechargeable types.
14.1 Battery Replacement
The battery cover is the large round disk shown in
the photo. This disk is also the Proble Zero Plate.
To remove it and expose the batteries, unscrew the
disk by carefully turning it counterclockwise.
Remove the old batteries and insert three
fresh AA batteries with the polarity as
indicated here (also shown on the label
on the back side of the gauge). Replace
the battery cover being careful not to over
tighten.
