How to change the display settings of the TS series torque meter from Nm unit system to kgfm unit system.
To change the display unit of the TS series torque meter, the following operational steps will be taken. Please refer to the respective manuals for specific operations.
1. Introduction
Due to the revision of the Measurement Law, the unit system has changed from kgfm to Nm. As a result, sales using the kgfm unit system are no longer possible, and specifications have been modified accordingly (fully implemented since October 1999).
(1) TS-3600/3100 Series Display Device
The unit system has been changed to only use Nm, removing the kgfm unit. The corresponding models will have a 'B' added to their designation to distinguish them from the conventional models. There are no other changes to the functions.
Supported models
TS-3600B、TS-3100B
detector
The nameplate of the detector has been changed from kgfm unit system to Nm unit system.
(Example) Rated torque → Rated torque value in Nm unit system
Factor → Factor value corresponding to Nm unit system
2. Method for displaying settings in the kgfm unit system.
If you would like to display in kgfm units on the customer side, you can do so by following the steps below. Please use the following calculation form for unit conversion.
Formula for Factor
Please enter the detector's Factor value (4-digit number) in half-width digits in the next text box and press the original unit button.
The converted Factor will be displayed below.
The calculation of Factor is done using
N·m unit system Factor = A,
kgf·m unit system Factor = B,
A = B × 0.9807, B = A ÷ 0.9807.
If you input full-width numbers, it will display 'NaN'.
(1) New detector + TS-3600B/3100B case
Set (Factor in Nm unit system) ÷ 0.9807 = (Factor in kgfm unit system).
(Example) (Factor in Nm unit system) = 8086 → 8245 (Factor in kgfm unit system)
Set the capacity from the detector capacity in Nm unit system to the value in kgfm unit system.
(Example 1) To set a rating of 200 Nm to 20 kgfm, set it to 200 → 20.
(Example 2) To set a rating of 5 Nm to 50 kgfcm, set it to 5 → 50.
Set the unit display from "Nm" to "−".
Make ZERO adjustments.
(2) New detector + unsupported TS case (TS-3100, 3100A, 3600, 3600A, 800, 800B)
It is a similar procedure to (1), but the unit in ③ can be set from 'Nm' to 'kgfm'.
(3) In the case of the old detector + TS-3600B/3100B
It is a similar procedure to (1), but in step ①, the nameplate of the old detector shows a factor in the kgfm unit system, so this value will be set as is.
(4) New detector + TS-2100/TS-2600 case
(Factor in Nm unit system) ÷ 0.9807 = (Factor in kgfm unit system)
Set the RANGE to the value on the nameplate. (The value of RANGE is the same in both Nm and kgfm unit systems.)
Shift the decimal point position by one digit. (The TS-2100 has no display.)
(Example 1) To convert 200 Nm to 20 kgfm, set it from 200.0 to 20.00.
(Example 2) To set the torque from 5 Nm to 50 kgfcm, set it from 5.000 to 50.00.
Prepare labels such as 'kgfm' and affix them in appropriate places for display.
We will perform a ZERO adjustment.
(5) In the case of the old detector + TS-2100/2600.
This is a similar operation to (4), but in step ①, the nameplate of the old detector displays a factor in the kgfm unit system, so this value will be set as is.
