I need to simulate a 5mV signal to a load cell input to simulate the output of the load cells why they are not wired up. My process fluke meter only has a mA output signal and does not have a mV output signal. Any ideas how I can simulate this desired 5mV signal at the load cell input.
Could I select an mA output on the meter and then calculate a resistor size to drop the 5mV across the resistor? For example if I output 20mA on my meter can I use 5mV/20mA = .25ohms and then use this voltage drop across the resistor as the input to the load cell input?
Could I use a 24V power supply with 2 resistors to create a voltage divider?
Do I need to take the input impedance of the load cell input into account when doing this?
