5. MAX/MIN function
Press MAX/MIN button to switch between MAX and MIN temperature.
MAX/MINMAX/MIN
6. Find heat and cold point
Aim the thermometer at target area and start to measure, then move up and down slowly to sweep the whole
area until the heat point and/or cold point are found.
7. D:S (Distance coefcient)
Limit 94 have D:S of 12:1 which means that if an object is measured from a distance of 12 m the instrument
will show the average value of 1m in diameter (shown below).
1@12
25@300 50@600 75@900
D:S = 12:1
2@24 3@36
8. Visual eld
Ensure that the target is larger than the diameter of the two laser spots. The smaller the target is, the closer
should the measurement distance be. Suggested measurement distance should be so the diameter of the two
laser spots cover less than 75% of the testing area (shown below).
