Combination milliamp simulator
and meter has numerous
pre-programmed operating modes
making this a versatile and
time-saving instrument. It has
user-programmable setups backed
up with non-volatile memory for
repeated special tests. Both the
simulation and measurement
modes operate with external
loop power supplies or with an
internal 24 V power source.
The CL28MA can be programmed
with either mA or percent-of-scale
data. When operating, the unit can
toggle between mA or percent
modes with the touch of one button.
Instead of fuses, the CL28MA is
protected with PTC resistors. These
devices automatically reset when
a fault condition is corrected.
Protection is provided between any
combination of terminations in the
input and output connectors.
