which one of the step/ramp modes has been selected.
4) Once enabled the step/ramp mode will run continuously until another
key is pressed.
B. Percent Error Mode
This unique feature will calculate error as a percentage of span (4 mA to 20
mA yields a 16 mA span). The percent error feature allows the user to
“Zero Out” the %mA display so that the deviation from the ideal value can
be displayed on the % error display. The procedure is as follows:
1) Connect the PCL120 to the unit under test.
2) Place the PCL120 in one of the mA output modes (source or simulate).
3) Adjust the PCL120 to the desired output.
4) If the unit under test does not read exactly as it should, hold down the
key and adjust the knob unit until the unit under test reads
correctly. Continue to hold down the
key.
5) The reading in the % display area will be the error or deviation
calculated as a percentage of span.
6) When the
key is released the % display will return to normal
operation.
C. Min/Max Datalogging
When the PCL120 is in any of the measure modes (mA, mA w/loop power
or voltage) it will continuously monitor and store the minimum and
maximum values for that particular input mode. To operate the
datalogging feature use the following procedure:
1) Place the PCL120 in one of the measure modes.
2) Connect the PCL120 to the unit under test.
3) Clear the min/max memory by pressing both keys (min and max)
simultaneously. The LCD will display “CLR” when the memory is
cleared.
4) Allow the unit to log min. and max. for as long as required.
Warning:
You may want to disable the Battery Save feature before using
the Dataloggiong Mode to prevent the PCL120 from turning off
prematurely.
5) At any time press the min. or max. to display the value stored.
6) Turning off the PCL120 or changing modes will clear the memory. Be
sure to record your data before turning off the unit.
