• Check the zero point adjustment again.
• The measuring chain is now adjusted and ready for operation.
Alternative setting
For 10V (4 … 20mA) output:
• Set OUTPUT switch to position +/-10V.
• Set 4 WIRE/6 WIRE switch to six‐wire configuration.
• Set EXCITATION switch to supply voltage 10V (factory setting).
• Set GAIN switch to position 4:

• Set ZERO switch to position 6 (zero = 1.730mV/V).
• Load the transducer with the required full scale and set the voltage full scale

).
• Check that V
out
= 10V (I
out
= 20mA) for the zero point, if this is not the
case, adjust the Gain (front) so that V
out
= 10V (I

= 20mA).
• Relieve the transducer, adjust Zero (front) to 0V (4mA).
• Check the amplification adjustment again.
• The measuring chain is now adjusted and ready for operation.
