% Scale of 4-20 mA or 0-20 mA
To display the current measurement in % scale, position your multimeter's rotary
switch to
the steps listed in "Measuring AC or DC Current" on page 85.
Table 2-14
[a] U1242C only.
The 4-20 mA current loop output from a transmitter is a type of electrical signal
NOTE
that is used in a series circuit to provide a robust measurement signal that is
proportional to the applied pressure, temperature, or flow in process control. The
signal is a current loop where 4 mA represents the 0% signal and 20 mA
represents the 100% signal.
The % scale for 4-20 mA or 0-20 mA in this multimeter is calculated using its
corresponding DC mA measurement. The multimeter will automatically optimize
the best resolution for the selected measurement. Two ranges are available for
the % scale as shown in Table 2-15.
