Instruction Manual – FA Series Force Gauge
Calibration is an important step when weighing the mass of an object. This process is used to adjust the force
gauge or scale to the actual gravity and barometric conditions of the user’s current location. It also accounts for
any drift due to temperature changes. To get to this function go to the Main Menu.
There are multiple methods that can be used to calibrate the gauge:
- Use an object of known weight to correctly adjust the scale.
1. Position the device upside down with the hook tip
attached. The gauge should be secured in the same
fashion that you plan to use it to weigh objects in (e.g.
locked into a stand, by hand, etc.).
2. Set the Mode to Mass
3. Select the Load weight exactly equal to the weight of
the calibration weight that will be used to calibrate.
4. Place the calibration weight on the hook or hook-held
platform.
5. Select Calibration – START to initiate calibration.
- Input the g-value (gravitational acceleration) of the location where the force gauge is
being used.
For this method, the exact g-value must be known and can be typed in using the arrow keys.
Note: The g-value of a given location can be found on the internet. (e.g. Wikipedia, a municipality site, etc.)
- Input the Geographical Location of where the force gauge is being used.
If the g-value is not known, the geographical coordinates can be entered.
1. Select Geographic Location
2. Enter the Latitude of the current location
3. Enter the Elevation of the current location
By entering these coordinates, the g-value will automatically be updated therefore calibrating the device.
Note: The geographical coordinates of a given location can be found through multiple methods including:
A GPS, Smart Phone Apps, and the Internet.
