2. Use the arrow keys to move the pointer to the recorder you want to
test and press [YES].
3. Enter the % of scale. If your recorder is set up for 4 to 20-mA,
enter 0 and press [YES]. If your recorder is set up for 0 to 20-mA
or 0 to 2-V output, enter 5 and press [YES].
Note: The recorders can not be trimmed to output a value of 0.00
mA/0.000 V due to the limits imposed by electronic noise. The
recorder output is typically 0.01 mA at zero output; therefore,
you should use 5% for the test value for 0 to 20-mA and 0 to 2-
V ranges.
