Abstract
Systems and methods for scale calibration. One example embodiment provides a system for calibrating a scale. The system may generally include an actuator for applying force to a platform of the medical scale, and an electronic processor communicatively coupled to the actuator. The electronic processor may be configured to control an actuator to apply, for a first interval, a first applied force having a first value greater than a target force value, and control the actuator to apply, for a second interval, a second applied force having a second value substantially equal to the target force value.
Claims20
A system for calibrating a scale, the system comprising:
- a human machine interface;
- and
- an actuator configured to apply force to a platform of the scale to simulate placing a weight on the platform;
- and
- an electronic processor communicatively coupled to the human machine interface and the actuator and configured to:
- (a) electronically control the actuator, to apply, for a first interval, a first applied force to the platform, the first applied force having a first value greater than a target force value representing an intended calibration force;
- and
- (b) electronically control the actuator to apply, for a second interval, a second applied force to the platform, the second applied force having a second value substantially equal to the target force value.
A system for calibrating a scale, the system comprising:
- a human machine interface;
- and
- an actuator configured to apply force to a platform of the scale to simulate placing a weight on the platform;
- and
- an electronic processor communicatively coupled to the human machine interface and the actuator and configured to:
- (a) electronically control the actuator, to apply, for a first interval, a first applied force to the platform, the first applied force having a first value greater than a target force value representing an intended calibration force;
- and
- (b) during the first interval, receive, from a load cell, an applied force value for the first applied force, wherein the applied force value is measured by the load cell;
- and
- (c) when a rate of change of the applied force value measured by the load cell passes a rate of change threshold, determine an end of the first interval.
A non-transitory computer-readable medium including instructions executable by an electronic processor to perform a set of functions, the set of functions comprising:
- (a) receiving a user input via a human machine interface, the user input including a target force value representing an intended calibration force;
- (b) in response to receiving the user input, electronically controlling an actuator, to apply, for a first interval, a first applied force having a first value greater than a target force value, wherein the actuator configured to apply force to a platform of the scale to simulate placing a weight on the platform;
- (c) electronically controlling the actuator to apply, for a second interval, a second applied force having a second value substantially equal to the target force value;
- and
- (d) when the second interval has expired, electronically disengaging the actuator.
