LIMITS
ISO 6789-1:2017
A.
To change the limit target value, use or in any measurement mode. The target value set
is shown on the display. Keep either key depressed for fast target value change.
B. The three calibration points (20%, 60% & 100%) are selected by pressing .
The percentage value selected is shown on the display.
To adjust a calibration point percentage value (e.g. change the first calibration point from 20% to 10%)
use
or whilst holding down .
The Pro-Test automatically calculates the limits to ISO 6789-1:2017 by the following method:
Deviation =
(Displayed reading
– Target value)
x 100
Target value
If the 100% target value is set above 10
N∙m, the deviation must be within ± 4%. For a 100% target value of
10
N∙m or below, the deviation must be within ± 6%.
Example: For a 100 N
∙m target value
Lower Limit = 96.0 N
∙m
Upper Limit = 104.0 N
∙m
TIP: For Indicating torque tools (Type I), the Pro-Test is designed for class B, C and E tools. Tools
of class A and D should only be used with capacities of 10
N∙m or below.
For Setting torque tools (Type II), the Pro-Test is programmed for Class A, B and C tools.
Tools of class D, E, F and G should only be used with capacities of 10
N∙m or below.
TIP: The max
imum target value in lbf∙ft (ft∙lb) is 50 lbf∙ft for the Pro-Test 60 and 300 lbf∙ft for the
Pro-Test 400.
