ero electronic DPS - C H - Analog Retransmission Maximum Range Value

d) Depress F pushbutton. The instrument memorizes the above
value as zero.
The display will show now "C H" which means that the instru-
ment is ready for next calibration step.
Fig. 5.8
NOTE: 1)The minimum value must be calibrated at 0 mA even if
the output is 4 - 20 mA.
2) For current output only, the D/A converter of the
instrument is not able to generate a negative signal;
therefore, during the calibration of this parameter, make
the instrument to generate a positive signal (by the ▲
pushbutton ), then decrease slowly the output signal (by
▼ pushbutton) until the lower value appears on the
display.
C H - ANALOG RETRANSMISSION MAXIMUM RANGE VALUE
a) Push ▲ and ▼ pushbuttons until the output of the instrument
is 20.000 mA
+ 0.015 mA or 10 V + 0.0075 V.
b) Memorize this calibration by pushing F pushbutton.
With this last operation the instrument returns at the beginning of
the calibration routine.
Switch off the instrument and set the dip switches according to
para. 4.1.
