The chart recorder output consists of a 12 bit digital to analog converter having
4096 steps for a 10 volt dynamic range. The settings entered at this menu level
determine the measurement resolution of the chart recorder output. The parameter
<Cal Step (V):> sets the step calibration value that is issued to the chart recorder
output when the command <Cal Step> is made active during the measurement cycle
( with <Chart Cal> active). The value entered for <Cal Step (V):> will apply for the
active engineering units of measurement from the data set <ppm>, <ratio>,
<Celsius>, <Fahrenheit>, <kelvin>, <Ohms> and <Volts>.
