Thanks GK and Edwin,

I appreciate your responses. In fact, I received a feedback from Seca, Germany regarding weighing scale calibration. We need to use atleast 2/3 of maximum weighing capacity of the scale. For example, if the scale could weigh a maximum of 150kg then the maximum weight used for calibration would be around 100kg. Therefore, one could choose 20, 40, 60, 80, 100kg weights for linearity and accuracy study. We have already implemented a form for recording atleast 4 -5 different readings with different weights.

Only lifting that much weight would be a problem for BME/BMRTs .

Edwin's suggestion is a good one but carrying the calibrated weighing scale from one place to another would be a cumbersome job but still better than lifting weights.

Now, the question is how to carry weights around the hospital to calibrate bariatric bed scales which weigh obese patients between 150 - 250kg .

Let us see how we perform our calibration in our forthcoming PPM on weighing scales and rely our experience to you.

Cheers
