Analog calibration values can be entered into the Model 350/355 by keying in the data in the left-hand column,
beginning at the line starting with “61200…”, replacing the “%s” character pairs with the ! key and “%e” with the
( key. The line with the “%c” is not adjustable and thus not enterable.
You can adjust the included factory recommended offset and gain values to precisely configure the system being
connected to these outputs. Once the initial factory values have been entered, pressing the ( key will cause the
count value to increase one count, and pressing the + 2 or ! keys will decrement the count value by
one count. All changes made are updated “live” to aid in calibrating a specific device to the analog option board output.
Holding down the key(s) will repeat the increment/decrement action.

Maximum analog output allowed
(entered in terms of voltage).
Since 7.166 v is less than 8 v (per P175), the output signal is not restricted and would be 7.166 v.
If a current output is selected, the output is a milli-amp current where 0 volts corresponds to either 0 mA or 4 mA (as
per P177) and 10 volts would translate to 20 mA. Values in between would be scaled proportionately:
Analog signal resolution: the output is the result of a 16 bit conversion resulting in a resolution of 1 part in 65535 or 10
/ 65535 = 0.00015 v.
