10 CALIBRATION
10.1 Initial Physical Setup
The sensor should be mounted vertically to a test stand or fixture rugged enough to withstand a load
equal to the full capacity of the sensor. Certified deadweights, torque arms/wheels, and/or master load
cells should be used, along with appropriate mounting brackets and fixtures. Caution should be taken
while handling such equipment.
10.2 Calibration Procedure
In the interests of simplicity and brevity, the following instructions use force terminology only. Such
wording is displayed only when a force sensor is being calibrated. When a torque sensor is being
calibrated, the terms
COMPRESSION
and
TENSION
are replaced by
CLOCKWISE
and
COUNTER-
CLOCKWISE
, respectively.
1. Select
Calibration
from the menu. The display appears as follows:
The sensor can be calibrated at up to 10 points in each direction. Enter the number of calibration
points for each direction (compression and tension or clockwise and counter-clockwise). At least
one point must be selected for each direction. For single-direction sensors such as Omega’s
Series RLC02, only one direction is allowed.
Note:
To achieve the accuracy specification of ±0.2% + sensor, it is recommended to calibrate
the sensor at 5 or more even increments in both the tension and compression directions. For
example, a sensor with capacity of 10 lbF should be calibrated at 2, 4, 6, 8, and 10 lbF loads in
each direction.
2. To escape the
Calibration
menu at any time, press
ESCAPE
. The display appears as follows:
Selecting “Cancel” will revert back to the Calibration setup. Selecting “Exit w/o saving” will return
to the menu without saving changes.
3. After the number of calibration points has been entered, press
ENTER
. The display appears as
follows:
