The display contains two lines of alphanumeric characters. The first line displays the numerical
value of the quantity described by the second line of the display. The second line contains the
units and a multiplier, which can range from 1 to 1,000,000. The multiplier is the value the
number on the top line must be multiplied by to achieve the correct value.
Three membrane keys are provided to operate
the display and program the meter.
When operating in the Run mode, the Scroll button
advances the display from one page to the next. A total

The Reset button (if enabled) allows totals to be reset to zero.
The Program button is not functional in the Run Mode.
