4.1 Connecting The Probe
Grasp the connector located at the end of the probe cable and carefully
insert the connector plugs into the receptacle located at the top edge of
the gauge. Make sure the connector is fully inserted into the recepta-
cle. The orientation of the plugs does not matter as they are non-
polarized. Refer to Section 3.8 for additional details
4.2 Turn On The Power
Press the key. All of the LCD Display elements will momentarily
illuminate. The firmware revision will then be momentarily shown
(for factory troubleshooting purposes only). Eventually the display
will show “0.000” (or “0.00” if using metric units), indicating it is
ready for use.
Note: 1. The gauge is turned off by pressing the key again.
2. The gauge will automatically power off after 5 minutes of
non-use.
3. All settings will be retained in non-volatile memory.
4.3 “Zeroing” The Probe
The Probe Zero Plate is used to “zero” the probe for calibration pur-
poses. Normally, this procedure is required only when the probe is
connected to the instrument for the first time, but since this process
takes less than 10 seconds, we recommend performing the Probe Zero
function occasionally as described below.
1. Check that the probe face (wear surface) is clean and free of debris.
2. Place a small drop of the supplied coupling fluid on the built-in
Probe Zero Plate located on the top of the gauge.
3. Press the probe firmly against the Plate.
4. The Stability Indicator on the LCD display should have six or
seven bars illuminated and a value should be shown in the display.
5. While maintaining probe contact with the Test Plate, press the
key. The display will show “Prb0” while the TI-25DL
calculates its zero point.
Note: The value shown on the display can be recorded and used in the
future to confirm that the gauge is functioning properly.
10.0 USING THE BUILT-IN DATA LOGGER
The TI-25DL incorporates a built-in data logging system that permits the
user to store up to 1000 data points. The stored data is grouped into 10
separate files (“batches”) with each file containing a maximum of 100
values. Each measured value is assigned a unique storage location within
the file. The user may download the stored data to a computer or to a serial
printer.
The end user must first select one of the ten (10) available files to store
measured values. The user normally would perform the following steps:
1. Select a File Number
2. Select a Storage Location within the file
3. Make a measurement
4. “Send” displayed measured valued to the Storage Location in the File.
Detailed procedures are provided in the following sections.
10.1 Storing Data
1. Turn on the TI-25DL power by pressing the key.
2. Press the key to activate the data logger. The display will alternately
flash “FILE” and “F-XX” (where “XX” is the File Number 01, 0...10).
Please note that there are 10 separate files (F-01, F-02 ... F-10)
3. Press the key to enter the file setup. The currently-selected File
Number will be displayed (F-01, F-02 .... F-10).
4. Press the key to select the currently displayed File Number or press
the or keys to index the File Number. When the desired File
Number is displayed, press the key to select it.
5. Press the key to advance to the first Storage Location (L001)
in the selected File. Press the or keys to advance to other
Storage Locations within the selected File.
The display will alternately flash the storage location (L-XXX, where
XXX is the storage location 001, 002 ... 100) within the selected File
Number. Each Storage Location can contain one of the following three
things:
• A measurement value that was previously stored
• A clear (empty) location indicated by the symbol “CLr”
