How to Set Tightening Torque on Torque Wrench With 42-210 Nm and 0-9 Scale?

Hello,

I got a torque wrench and I have a problem with how to set the tightening torque. The key has a scale from 42 to 210 with a division every 14 Nm. (42, 56, 70, 98, 112, 126, 140, 154, 168, 182, 196, 210). on the movable part around the circumference there is a scale from 0 - 9 and again 0 - 9. The key is supposed to be accurate to 1 Nm. I set the key so that the sliding scale with the value 0 coincides with the value 42, the lowest. To set the next value (56), I should probably theoretically turn the key by 14 dashes, at this point the constant value 56 coincides with the number 4 on the key, and it would probably be correct. But when the key is open, to set the value of 56, I should turn it to 0 or count from the value of 42, 14 dashes, etc.

42 to zero plus 14 dashes and that's exactly the same as 56 to zero

yes, but if I set 56 starting with 42, then I will have 4 on the moving part, so is it the same as I set 0 on 56 at once? will it not be a difference of 4 Nm?

Well, probably simple on the scale you have dozens of newtons and on the knob unity.

I understand it, I have 42 dozen and add 14 units. I have 56 on the key and 4 on the handle, so if I want to set 56, I set zero immediately or do I have to count from the beginning of 14. and if I set 70 also 0 or I go from 42 28 units, which will give me 70 on the key and on the handle 8. I set the next value 84 from 0 do I count from 42 on the key 42 units, which will give me on the knob 2. so I rather can't set the value on the key with the knob to 0 because counting from 42, only in two tens it will be equal to zero on the handle. so how can I set the value of 210 to zero if by setting the same value starting from 42 I have to add 168 units and it will be equal to 8 and not zero. After all, 0 is not 8 and vice versa.

value: 98 = 42 + 56 units on the handle = 6
112 = 42 +70 units on handle = 0
126 = 42 + 86 units on handle = 6
140 = 42 + 98 units on the handle = 8
154 = 42 + 112 units on handle = 2
168 = 42 + 126 units on handle = 6
182 = 42 + 140 units on the handle = 0
196 = 42 + 154 units on the handle = 4
210 = 42 + 168 units on handle = 8

I confused it a bit but I hope someone will find out what I mean

How can this not be understood. A few of your examples.
98 Nm equals 98 on the scale + 0 on the handle
140 Nm is 140 on the scale + 0 on the handle. now my examples.
60 Nm is 56 on the handle + 4 on the handle
190 Nm is 182 on the scale + 8 on the handle.
I hope you understood.

As you can see, buddy - you can not understand
I will just add that after finishing work, the key should be zeroed, i.e. set to zero. They are calibrated - remember, this is not an ordinary "rattle"!

your examples

60 Nm is 56 on the handle + 4 on the handle - if I have 0 on the handle by setting the value of 42, then with the value of 56 I will have 4, so adding another 4, I already have 18 counting from 42, i.e. on the handle 8. So I can not set the value 56 with zero on the handle and then add 4 because in my opinion it will be 56 and not 60, and 0 on the handle with a value of 56, it will probably be 52

190 Nm is 182 on the scale + 8 on the handle. I agree here, this is the second case in which, counting from 42, 0 appears on the handle.

there would be no problem if the values on the key were every 10 instead of 14.

the question is whether to count from 42 units to set the desired value. Besides, I would like to remind you that there are two 0s, two 1s, two 2s etc. on the handle, so how do you know which 1, 2, 3, 4, 5 etc. to set. The jump is not great and you can swing by 10 Nm. the entire turn of the handle is 20 Nm.

Not only that, a friend even called a friend of the diagnostician who said that he had not seen such a stupid key yet

tomorrow, maybe I will be able to upload photos and then it will probably be easier to explain what I mean.

Gebeo on the handle you have double values because the graduation is in two columns. By turning the handle you reach zero from the handle to the value on the scale, e.g. 56 and add 4 by turning the handle and you have 60.
I can't explain it more easily.

Added after 30 [seconds]:

You must have read the instructions for this key.

Well, that's why you have 14 lines on the scale, so as it was said, from 42 plus 14 lines you have 56 or zero at "56Nm" 56 plus 14 etc.
It really cannot be easier, it is probably the most popular key because of its price.

This is the problem.

Gebeo and how did you already master this key?

Despite the comments on the topic, I would like to thank the moderator for the warning.
Apparently interested in the topic, he does not read it, except for the helpers, which does not affect the solution of the problem anyway.
Thank you and I recommend myself to Błażej.
