The calibration display of Figure 8656.1 is a single form containing all the information necessary to calibrate the asphalt
meter by weighed loads.
The upper left portion of the display shows Test Parameters. The desired rate at which the asphalt is recirculated and will
be pumped is specified by the first parameter in TPH. The density of the sample asphalt is specified by the second
parameter in lb/gal (at 600F). The length of time the divert valve will be switched to the RUN, ie sample, position can be
preset with the time interval parameter shown in seconds.
The Measured Meter Values are displayed in the lower left portion of the display. These are the display of the
instantaneous pumping rate, the asphalt temperature, and the accumulated wet tons.
The actual procedure is defined by the continuation options in the order shown.
