Measuring or Sourcing with Custom
Units
w Warning
To avoid possible electric shock, when
using Custom Units for measurement,
always refer to the secondary value
displayed below and to the right of the
main display for the actual value of the
measurement in native engineering units.
You can set up the measurement or source display
to show your own custom units. To do this, you
select a function, for example mV dc, scale it as you
choose, then enter an alphanumeric name for your
custom units, for example, “PH.”
Proceed as follows to set up a custom unit:
1. When measuring or sourcing the function of your
choice, press the
Scale softkey, then select
Custom Units from the list.
2. Enter the 0% and 100% scale points for the input
of your transfer function.
3. Press the Custom Units softkey.
4. Enter the 0% and 100% scale points for the
output of your transfer function.
5. Enter the name of the custom units (up to four
characters), for example
PH (for pH), using the
alphanumeric entry window, then press e .
While Custom Units are active, the w symbol shows
on the display to the right of the custom unit. Once
you have programmed the custom measurement
unit, the custom unit is available for calibration
procedures in split-screen MEASURE/SOURCE
mode. To cancel
Custom Units , press the
Custom Units softkey again.
