D) TX MEASUREMENT
The TX measurement is a mA measurement with a 24 V power
supply generated by the instrument and is used to calibrate 2, 3 or
4-wire transmitters.
Power supply: 24 V DC (maximum current 24 mA)
Resolution: 1 mA.
Reference accuracy: 0.015 %
Input impedance: 10 W for mA input
Input range: 0 to 20 mA
Square root extraction: programmable
Read-out: keyboard programmable from -20000 to 20000.
Decimal point: programmable in any position.
E) W MEASUREMENT
Ranges: from 0 to 800 W.
Resolution: 0.1 W.
Reference accuracy: the accuracy is shown as a percent of the
specified span.
