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.
Claims18
A method for calibrating a scale, the method 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.
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) receive a user input via the human machine interface, the user input including a target force value representing an intended calibration force;
- (b) control the actuator to apply, for a first interval, a first applied force having a first value greater than a target force value;
- (c) control 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, disengage the actuator.
A method for calibrating a scale, the method comprising:
- electronically controlling an actuator to apply, for a calibration interval, an applied force having an applied force value substantially equal to 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;
- during the calibration interval, receiving, from a load cell, an applied force value for the applied force;
- when the applied force value is less than the target force value by a first threshold, electronically controlling the actuator to increase the second applied force to the target force value;
- and
- when the applied force value is greater than the target force value by a second threshold, electronically controlling the actuator to reduce the second applied force to the target force value.
