The CA71 is a small, lightweight,
multifunction calibrator that can
simultaneously source and
measure voltage, current,
resistance, thermocouple, RTD,
frequency, and pulse signals.
Rotary switches allow for easy
operation. Upon opening the
carrying case cover and connecting
the cables, the user is ready to take
measurements.
The CA71 offers many useful
functions, including source
(output can be set in steps);
power; transmitter; divided (n/m,
eliminating need for calculations
for percentage output); autostep
(changes can be sourced every
10% or 25%); online communication
(RS232); sweep (linearly changes
output over 16 or 32 seconds);
memory (50 sets); and temperature
monitor.
