The CA71 Calibrator is a small,
lightweight, multifunction calibrator
that can simultaneously source
and measure voltage, current,
resistance, TC, RTD, frequency,
and pulse signals.
The Calibrator incorporates rotary
switches for simple handling. Just
open the carrying case cover and
connect the cables, and you're
ready to take measurements.
A wide array of useful functions
are offered, 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 function.
