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.
•
A 2-Point, 3-Point or a 4-point calibration can be performed. A third or fourth point is only necessary when high accuracy is
required at temperatures of 300°F and higher. You must have the proper equipment for every point of calibration.
•
Do not attempt to calibrate the instrument if the
properly stored 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 certified reference thermometer.
•
Warm to hot fluid bath between 20°C (approx 68°F), or higher up to 90°C (approx 194°F) with certified reference
thermometer. (see Note)*
•
Optional high temperature oil bath at about 150°C/300°F and certified 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"
calibration can be made near that temperature. Temperature accuracy above this calibration point cannot be assured.
