Abstract
The invention provides a compact electronic timing device for indicating procedural steps to be taken during the setting of a settable mixture which is to be formed by mixing two or more components in a mixing zone separated from the device. The mixture passes through a plurality of successive stages from mixing to setting, at least one stage having a duration which is temperature dependent. The device includes: a display having a plurality of portions, each portion corresponding to a stage through which the mixture is to pass; a timer having a manually operable starter; an indicator operatively linked with the timer and associated with each portion of the display for indicating the lapse of time during each stage; a temperature sensor for sensing the ambient temperature in the environment of mixing; and a controller arranged to received data from the temperature sensor and data from the timer, and arranged to provide an output, responsive to the received data, for controlling the indicator, such that the indication of the lapse of time during at least one of the stages is dependent upon the ambient temperature.
