HANDLING
General advice
Clean only with a damp cloth. Do not wet or allow moisture to penetrate the unit. Do not use solvents or abrasive
materials.
Please store the measuring instrument in a dry and clean place.
Avoid any force like shocks or pressure to the instrument.
Do not use force to connect the probe or interface plugs in.
If no sensor is connected to the instrument while switching on, “open” shows on the display (Please refer to chapter
error codes/troubleshooting).
A retractable stand on the back of the instrument allows it to be used as a bench top instrument.
This equipment contains no user-serviceable parts. Refer all repairs to qualified service personnel. Contact Isothermal
Technology or one of our appointed distributors for details of approved service outlets
Operation
Before switching on the instrument, connect the probe or probes to the instrument
and insert the battery (Please refer to Power supply/changing the battery). The input
connectors are labelled “1” and “2”.
Switching on and off
By operating the ON/OFF-key the instrument switched on or off. After switching on
the instrument indicates a full segment test for 15 seconds, then it starts to function in
measurement mode indicating the actual measurement value.
Menu
The adjustments of the instruments function such as measurement value, calibration of probes, deactivation of
channels are selected from the menu structure. Enter into the main menu by pushing [ENTER/MENU]. Use the up
and down keys [] to select the required menu. Push [ESC] to revert back to the measuring mode.

Calibration function / [CAL]
The TTI-10 has different calibration options that allow the instrument to be matched a thermometer. When the TTI-
10 is a calibrated with a probe or probes at Isotech the calibration options are removed to prevent accidental or
unauthorised change. The display will indicated that the calibration is active by showing [CAL] and the calibration
option for each Channel, e.g., [CAL]22 indicates that calibration mode 2 is active for both channels.
Should access to the calibration options be required please contact Isotech for details of how to enable the calibration
menu.
If the instrument has not been calibrated with a thermometer at Isotech then the calibration options will be
accessible.

The instrument offers different calibration options:
1) [OFF]: No corrections are applied. (EN 60751)
2) [OP1]: Calibration by code (2 x four digit code) is equivalent to a 2-point calibration.
3) [OP2]: Recommended Mode: Calibration by Comparison to a Standard Thermometer (1-point, 2-point or 3-
point calibration)
4) [OP3]: Calibration according to Custom Probe Coefficients (EN60751)
5) [OP4]: Reserved for future use
To Change Calibration Mode
Push [ENTER/MENU] to calibrate the instrument with sensor. Use the up and down keys [] to select CAL. Push
again [ENTER/MENU]. On the left corner of the display appears a small 1, which indicates the selected channel. To
change the channel use the up and down keys []. Push [ENTER/MENU] to confirm

Example of a 1-Point calibration:
Push [ENTER/MENU] to confirm. On the display appears CALC. After the displayed measuring value is stabile push
[ENTER/MENU]. On the first display line you can see the “frozen” measurement value. On the second line as a
default you can see -100.000. Now you have to Enter (instead of -100.000) the correct measurement value from
your reference:
By using the up key [] you are able to move the decimal point to setup the number of decimal places. Push
[ENTER/MENU] to confirm.
Now the algebraic sign is blinking„-„. Use the up key [] to toggle for positive or negative number. Change the
number using the up and down keys [].
Note:

Push [ENTER/MENU] to confirm, revert back to the measuring mode.
Important: A break of the physical calibration cannot be done by the [ESC]-button.
Display-indication with active calibration code (OP2):
The CAL-segment and the small 2indicates to the user that oP2 is activated.
4) Calibration according to Coefficients of EN60751 (R0,ABC)
By using Option 3 you are able to activate coefficients according to EN60751 (R0,A,B,C). The coefficients have to be
calculated using special software on a PC (e. g. P7_CALC). Before you are able to activate this option you have to
transmit the coefficients from the PC to the instrument.
Use the up and down keys [] to select oP3. Push [ENTER/MENU] to confirm.
Now the calibration option 3 is activated. Push [ESC] to revert back to the measuring mode.

Recalling the memory data (HOLD MAX MIN AVE)
After pushing first time the key [HOLD MAX MIN AVE] the actual values will be held on the display. Pushing again the
key [HOLD MAX MIN AVE], the saved maximum-, minimum and average values will be displayed.
Note: During the recall of the memory data the extremes (MAX MIN) and the average value (AVE) will not be
calculated or carried on.
Clearing the memory (MAX MIN AVE)
Press [CLEAR] key once to erase the stored maximum, minimum and average from memory. On the display appears
Clr. –After erasing the memory the instrument automatically reverts back to measuring mode indicating the actual
measured value again.
Measuring rate (Normal-Mode/FAST-mode/Filter-Mode)
The instrument has three different response times to select:
Normal-Mode: high resolution (0,001 from -199,999 to +199,999)
Fast-Mode: reduced resolution (0,01 from -199,99 to +199,99)
Filter-Mode: high resolution (0,001 from -199,999 to +199,999)
Press [FAST/] key to change the measuring rate.
By using the Filter-Mode the instrument is performing a moving average to stabilize the displayed measurements.
After turning on the instrument it is in the Normal-Mode. After pressing once the [FAST/] key the instrument
switches to the Fast-Mode. Pressing the same key once again the instrument switches to the Filter-Mode.
E.g. Display with activated Filter-Mode:
The arrow on the top indicates that the instrument is working in the Filter-Mode.
Note: After switching off the instrument, this function is automatically deactivated.
AUTO-OFF-function
EAoF = Enable Auto-off
dAoF = Disable Auto-off
Press [ESC/AUTO-OFF] key once. On the display appears EAoF. Now the instrument switches off automatically
after app. 30 minutes. Press [ESC/AUTO-OFF] key again. On the display appears dAoF. Now the Auto-Off-function
is deactivated.
Note: After switching off the instrument, this function is automatically deactivated.
