3.7 Test Plate
When first connecting the probe supplied with the TI-25DL, the user
should perform a “Probe Zero” as described in Section 4.3. The Probe
Zero Test Plate is used for this task. It is located on the top edge of
the gauge as shown in the photo below. It also serves as the battery
compartment cover
Note: The thickness of this plate is not imporatnt, and it should not be
used as a Calibration Test Plate. A precision 4-step Test Block is
optionally available for this purpose.
3.8 Probe Receptacles & Probe Zero Plate
Located on the top edge of the
TI-25DL housing are the
receptacles for the probe and
the probe zero plate.
The connectors for the probe
are non-polarized so the con-
nector at the end of the probe
cable can be inserted into this receptacle in either orientation. Make
sure the connector is “well seated” in the receptacle.
3.9 Battery Compartment (Changing The Battery)
The battery compartment is located
under the probe zero test plate. To
open the battery compartment,
unscrew the probe zero plate by
rotating it counterclockwise. The
TI-25DL operates on two (2) AA
Batteries (1.5 V). If desired,
rechargeable batteries may be used.
The TI-25DL is shipped with the batteries installed. Insert batteries in
the polarity indicated on the rear label.
Note: When the display elements begin to flash off and on repeatedly,
the batteries are low and should be replaced.

• An obstruct condition indicated by the symbol “ObSt”. An obstruct
condition is recorded when a user has pre-assigned storage locations
to measurement locations and a measurement could not be obtained
(for any reason) in this location.
6. Take a measurement and press the key to store the measurement in
the previously-selected storage location.
Note: The data logger will automatically advance to the next storage
location within the file.
7. Repeat step #6 as many times as desired.
If the “FuLL” symbol is shown on the display when attempting to store a
measurement, the data logger is advising the user that the currently-selected
storage location already has a measurement stored. The user should first
clear the storage location (refer to Section 10.2) or select another unused
(empty) storage location for the measurment.
10.2 Clearing Individual Storage Locations
Data in any individual storage location can be cleared (erased) and replaced
by another measurement or left empty. The procedure for clearing a storage
location is as follows:
1. Advance to the storage location that is to be cleared by performing the
steps #1 through #5 in Section 10.1
2. Press the key to delete the measurement currently stored in this
location. The display will alternately flash the storage location (L001 ...
L100) and then the “CLr” symbol.
3. Take another measurement and press the key to store it in the
location that was just cleared.
10.3 Clearing The Contents Of A File
When desired, a user may erase (clear) the content of an entire file. This will
permit the end user to store a new series of measurements in this file starting
storage location L001. The procedure to clear the contents of an entire file is
as follows:
1. Turn on the TI-25DL power by pressing the key.
