CALIBRATION PROCEDURE
The calibration mode should only be accessed by qualified personnel with proper equipment; otherwise
calibration integrity may be compromised. Read the following instructions carefully.
At least 2 points are required to make an adjustment. (2-Point calibration). Additional points can be taken
(3-Point or 4-Point calibration) to calibrate a large range of temperatures (e.g. 0°F to 300°F) or if you want
to match specific points in your range. You should include points at the bottom and top of the range. You
must have the proper equipment for every point of calibration.
Do not attempt to calibrate the instrument if the low battery indicator has been displayed since the new
calibration values may not be properly s tored to memory.
Refer to API 7.2 or another recognized standard for routine calibration verification recommendations.
Calibration must not be performed in any environment considered to be hazardous.
Equipment needed:
Ice Bath or other low temperature bath with reference thermometer.
Warm to hot fluid bath between 20°C (approx 68°F), or higher up to 90°C (approx 194°F) with reference
thermometer. (see Note)*
Optional high temperature oil bath at about 150°C/300°F and reference thermometer.
*Note for limited calibration: If entire range capability of instrument is not required, the 2 point high adjustment
can be made at a temperature relatively close to the common temperature of the liquid measured and accuracy
will be maintained within the limited range. For example: If liquid product to be measured is commonly less than
38°C (approx. 100°F), then a “high point” calib ra t io n c a n be made near that temperature. Temperature accuracy
above this calibration point cannot be assured.
To calibrate proceed with the following steps:
1. Enter calibration mode by going to CALIBRAT in the selection Menu. When this is selected, the user will be
prompted to enter a 3 digit password. Using the “up/down” buttons allows each digit to be adjusted. Once the
correct value is set, advance to the next digit by pressing the “select” button. After the 3
“select” button to enter Calibration mode. If an incorrect password is entered, FAIL will display and the unit
will return to temperature mode. Once in Calibration mode the ‘CAL’ icon on the display will blink. The
calibration mode password is: 112
2. Select ADJUS
2PT CAL, 3PT CAL or 4PT CAL using the select button.
T from the calibration menu and then select the desired number of calibration points. Pick
NOTE: If the user is not ready to enter the calibration mode, the EXIT option can be chosen.

3. T
he device is now in adj ustm en t m ode . The di spl ay will show ADD PT1. The “up/down” buttons can be used
to select a different point to adjust or CANCEL. If the CANCEL option is chosen then the calibration
procedure is exited and the prior calibration values are re-activated.
ADD PT1 = Lowest temperature point
ADD PT2 = the next higher temperature point
ADD PT3 = the next higher temperature point (only used in 3-point calibrati on or 4-point calibrati on mode)
ADD PT4 = the highest temperature point (only used in 4-point calibrati on mode)
ADJ DONE = Save and exit calibration mode (all points adjusted & valid)
CANCEL = Exit calibration mode without saving
Pick which point to adjust and press the select button to begin. The current temperature will display and the
CAL icon and the number of the point to adjust will now be blinki ng.
NOTES:
o Calibration can be performed to hundredths of a degree.
o The up/down buttons can be used to increase or decrease the display reading.
o Holding the up/down buttons adjusts 0.1 degrees increments.
o Momentary Presses of the up/down buttons for less than 0.5 seconds adjusts 0.01 degrees for every
press.
o The display arrows will flash 3 times when the temperature reading has stabilized.
o All points must be saved before selecting ADJ DONE. A DATA ERR message will display if all
points have not been saved or are not in increasing temperatures. (Ex: PT1 = 32F, PT2 = 120F, PT3
= 250F)
o While in calibration mode the temperature will display based on the prior calibration curve.
o The RESETCAL feature can be used to return the unit to a factory calibration curve.
(calibration/adjustment will still be required ).
o The RESETCAL (reset to factory calibration) feature should be used i f th e pro be is repl a ced usi ng
a 2-wire assembly instead of a 3-wire assembly or if prior calibration has caused the unit to read
excessively out of tolerance.
4. Once the temperature has stabilized, using a reference device check the actual temperature in the bath and use
the “up/down” buttons to adjust the device to the a ctual temperature. Once the device temperature matches the
actual temperature, press the select button to save the set ti ng. The display will show SAVE or EXIT. If
EXIT is selected it will return to the ADD PT1 menu. Once SAVE is
selected the display will advance to the
next temperature point for adjustment showing ADD PT…. The up/down buttons can be used to select a
different point to adjust or CANCEL. If the CANCEL option is chosen then the calibration procedure is exited
and the prior calibration values are re-activated.
o NOTE: Once SAVE is selected the temperature display will return to the previous reading until the
calibration is completed.
o NOTE: If SAVE is selected before the temperature has stabilized, the display will show NOT
STABLE. Wait for the temperature to stabilize before saving.
5. Move the probe to the next bath and repeat step 4. After you save the highest temperature point the display
will flash READY and the new calibration settings will be in effect. The buttons will now resume their
normal operating functions. The calibration setti ngs are saved to flash memory when the device is turned off.
The unit will not turn off automatically. Manually turning the unit off saves the calibration data.

SAFETY APPROVALS FOR TP7-D AND TP9-A:
AEx ia IIB T4 Ga
Applicable Standards are: Agency or Safety Designation
IEC 60079-0:Ed 6, IEC 60079-11:Ed 6 IECEx
EN 60079-0:2012 + A11 3013, EN60079-11:2012 Europe: ATEX
INTRINSIC SAFETY
Intrinsically safe equipment is defined as "equipment and wiring which is incapable of releasing sufficient electrical
or thermal energy under normal or abnormal conditions to cause ignition of a specific hazardous atmospheric mixture
in its most easily ignited concentration." (ISA-R P1 2.6 ) This is achieved by limiting the amount of powe r avai l a bl e t o
the electrical equipment in the hazardous area to a level below that whi ch will ignit e the gas es.
In order to have a fire or explosion, fuel, oxygen and a source of ignition must be present. An intrinsically safe system
assumes the fuel and oxygen is present in the atmosphere, but the system is designed so the electrical energy or
thermal energy of a particular instrument loop can never be great enough to cause ignition.
