Siglent SPD3303X(-E) calibration FW1.01.01.02.07R2 - best practice

<< < (9/10) > >>

Wade2019:
I have an SDP3303D and I use the statement CALibration: VOLTAGE ch1,1,0.8613. The beep of the buzzer does not work. I use the following statement: CALibration: VOLTAGE ch1,1,0.8613 CAL:VOLT ch1,1,0.833   No effect, who can help me? |O |O |O

LXI is case sensitive AFAIK. Maybe it trips on VOLTAGE instead of VOLTage Try:

CALibration:VOLTage ch1,1,0.8613


Wade2019:
I tested SCPI:

CAL:VOLT ch1,1,0.833     ERROR  The beep of the buzzer
CAL:VOLT ch1,1,0.83311     ERROR  The beep of the buzzer
CALibration:VOLTage ch1,1,0.8613   ERROR  The beep of the buzzer
CALibration:VOLTage ch1,1,0.861   ERROR  The beep of the buzzer

I am using the software NI MAX and my power supply is SPD-3303D    Seeking everyone's help

SuperD:
This is for anyone getting the beep every time they send the voltage calibration command. I have hardware V3.0, and downgrading to firmware version 1.01.01.02.05 is what fixed this for me. .07R2 doesn't do anything I need, so I am keeping it here.

I had no issues setting 4 decimal positions like below. I think its all firmware related. I guess never trust an "R" or "B" in the firmware number.

With firmware version 1.01.01.02.05, calibration commands are accepted without errors.

My calibration commands:
CAL:VOLT CH1,1,0.8195
CAL:VOLT CH1,2,25.5040
CAL:VOLT CH2,1,0.8060
CAL:VOLT CH2,2,25.5015

As long as you can measure accurately the load current, a resistor would be more stable.

What kind of "beefy" resistors would I be looking at purchasing for testing the DC current?
What wattage it needs to be able to handle? And what tolerances should I be looking at?
