indicated by the value 9.9E + 37 instead of the normal voltage or power readings. This is the IEEE 488.2 value for positive infinity.
CC Mode Example
This example selects channel 1, sets the current level to 1.25 amps and then reads back the actual current value.
10 OUTPUT 705; "CHAN 1"
20 OUTPUT 705;"INPUT OFF"
30 OUTPUT 705;"MODE:CURR"
40 OUTPUT 705;"CURR:RANG MIN"
50 OUTPUT 705;"CURR 1.25"
60 OUTPUT 705;"INPUT ON"
70 OUTPUT 705;"MEAS:CURR?"
80 ENTER 705;A
90 DISP A
100 END
Line 10: Selects the channel 1 module.
Line 20: Turns off the input.
Line 30: Selects the CC mode.
Line 40: Selects the low current range.
Line 50: Sets the current level to 1.25 amps.
Line 60: Turns on the input.
Line 70: Measures the actual input current and stores it in a buffer inside the Multiple Electronic Load.
Line 80: Reads the input current value into variable A in the computer.
Line 90: Displays the measured current value on the computer’s display.
CV Mode Example
This example selects channel 2, presets the voltage level to 10 volts, and selects the external trigger source. When the external trigger signal is received, the channel 2 CV level will be set to 10 volts.
10 OUTPUT 705; "CHAN 2;:INPUT OFF"
20 OUTPUT 705;"MODE:VOLT"
30 OUTPUT 705;"VOLT:TRIG 10"
40 OUTPUT 705;"TRIG:SOUR EXT"
50 OUTPUT 705;"INPUT ON"
60 END
Line 10: Selects channel 2 and turns off the input.
Line 20: Selects the CV mode.
Line 30: Presets the voltage level to 10 volts.
Line 40: Selects the external input as the trigger source.
Line 50: Turns on the channel 2 input.
