Gripping Force Meter SKM 1200 and SKM 1500
|

|
Technical Details
The SKM 1200 and SKM 1500 gripping force meters meet the EMV
regulation 89/336/EWG and are marked with the CE-sign to indicate
conformity with the relevant European safety standards.
The gripping force meter automatically carries out an adjustment
of the zero-point when it is switched on. If the zero-point
has been displaced by more than 20% of the maximum measuring
range value the display flashes. This indicates previous mechanical
overloading of the gripping force meter and lasting distortion
of the measuring bolt. In this case, the meter should be returned
to FORKARDT for testing and maintenance.
A second set of tension and compression bolts is required
for testing 6-jaw chucks. The corresponding part order numbers
can be found in the ,,Accessories" section.

Key-Functions
 |
Record maximum
value
The maximum value recorded is stored and displayed. Maximum
value mode allows to take a reading in chucking situations
when the display cannot be viewed. The maximum value remains
displayed after unclamping the meter. The memory can be
cleared before a new maximum value reading is taken by
pressing the CLR button. If the memory isn't cleared manually
it will be cleared automatically whenever the next reading
is taken and the new result will be displayed. In order
to avoid misinterpreted readings, the maximum recorded
value is automatically deleted, whenever the meter is
switched off. |
 |
Changing number
of jaws
The number of jaws changes each time this key is pressed.
The chosen number of jaws is shown in the top right corner
of the display. Possible values are 2, 3 and 6 jaws. The
reading eventually displayed is the actual measurement
multiplied by the number of jaws selected, and the maximum
value is cleared. |
 |
Clear maximum value
The recorded maximum value is cleared, but the unit remains
in maximum value mode. |
 |
Changing the unit scale
On pressing this button the unit scale is changed. Available
unit scales are t, kN and klbs. The value read is recalculated
and displayed when the unit scale is changed.
1 kN = 1000N, 1 t = 9807 N, 1 klbs = 1000 lbs = 4448 N |
 |
Switching on / off
Current settings remain stored when the meter is switched
off. Upon switching it back on, measuring operations can
be started immediately. |
 |
Adjusting the zero-point
The zero-point on the meter is adjusted by pressing this
button. This function should only be used when the meter
is not clamped or loaded. |
