OPOS scales - how to check health

Question

I'm iitializing and reading weight from OPOS scales (digiscales). In case scales are for some reason ejected (cable) and connected again, reading weight starts returning always 0. How can I catch this event (possible checking health) to close and re-initialize scales?

Have tried to catch any error in check health (passing different parameters to checkhealth) - it still doesn't throw error on eject:

            {
                _scale.CheckHealth(0);
                _scale.CheckHealth(1);
                _scale.CheckHealth(2);
            }
            catch (Exception ex)
            {
                _logger.LogInformation($"OPOS scales: health check failed with message: {ex.Message} {ex.InnerException.Message}");
                CloseScale();
                return 0;
            }
