4.3.6. Simulating of a transducer
CAUTION
In this mode the instrument generate a output current up to 24mADC. It is
necessary the use of a external power supply with 30VDC maximum voltage
to perform the adjustment of the current
Fig. 7: Simulating of a transducer
1. Press INPUT/OUTPUT key and select the generation mode. The “OUTPUT” symbol is
displayed
2. Press mA/% key and select the desired measurement unit. The symbol “mA” or “mA%”
is displayed
3. Insert the red plug into V jack and the black plug into COM jack
4. Connect the red and black test leads respectively to the positive of the external power
supply and positive pole of the external measurement device (e.g. multimeter – see Fig.
7)
5. By means arrow keys
 and  (see Fig. 1 – parts 9, 10, 11 and 12) to set the value of
output generated current. The maximum set value is 24mA DC with DC voltage fixed to
24V DC. For the “mA%” output consider that -25% = 0mA, 0% = 4mA, 100% = 20mA
and 125% = 24mA. The current value will be displayed
6. For the generation of a negative value of current connect the test leads in the opposite
direction than shown in Fig. 7
