11 CALIBRATION
11.1 Initial Physical Setup
The TT01 should be mounted to a fixture rugged enough to withstand a load equal to the full capacity of
the instrument. Suitable certified calibration equipment is required, and caution should be taken while
handling such equipment. A calibration kit is available from Mark-10.
11.2 Calibration Procedure
1. Select
Calibration
from the menu. The display will appear as follows:
The tester can be calibrated at up to 10 points in each direction. Enter the number of calibration
points for each direction. At least one point must be selected for each direction.
Note:
To achieve the accuracy specification of ±0.3% of full scale, it is recommended to calibrate
the TT01 at 5 or more even increments in both the clockwise and counter-clockwise directions.
For example, Model MTT01-50 (with capacity of 50 lbFin) should be calibrated at 10, 20, 30, 40,
and 50 lbFin loads in each direction.
