2.5. Generation or Output Functions

28
Select through the menus the type of signal to be generated and use the corresponding terminals:
a) OUT
Press ENTER to select volt generation, press , ,  and ➔ to select another signal.
OUT = x.xxxx V Display indicates the output value in volts. Signal may be inverted by using key 0 (+ / -).
C/CE
For the RTD or OHM generation, the calibrator simulates electronically a resistance value, that is, there is no
resistor but an electronic circuit which behaves as a resistor. It was designed specifically with the purpose of
simulating RTD so that the resistor can be connected to instruments such as indicators, transmitters, temperature
controllers, with an excitation current within the range of 150 µA to 5 mA. For the OHM generations, you should
choose between the range of 400  and 2500 .
For the thermocouple generation, you should choose the type of thermocouple and the type of cold junction
compensation.
The F option at the output allows you to select frequency generation (10000; 100.00) (Hz) or pulse
generation (counter). In frequency generation, you may set the amplitude (Level) of the signal, square wave, which
ranges from 0 to 22 V. For the pulse generation, in addition to the amplitude (Level) and number of pulses (#), you
should provide the rate at which pulses must be sent, in Hz. The pulse sequence is sent as soon as ENTER is
pressed to confirm the rate at which pulses are emitted. When the arrow key
shown the rate at which pulses are emitted.
The OP option is the same as it is described for input functions.
The NO option deactivates the output function.
Selects the output functions.
