I have two Siglent SDM3055 bench meters and they have "rel" feature, can be used for example to offset low resistance measurements where the lead's resistance could effect the readings.
But its confusing, it can be used for other kinds of measurements and the manual say very little about it:
One can press Math and in that menu see a "Rel Value" that can be "Off" or some value. Also in many modes like DC volts or resistance etc, one can also access a "Rel" setting and set it either on or off.
But its confusing, like if I go to Math and select Relative, it seems to have the ability to take the current reading as the relative value and save that, but it see inconsistent, and I cannot really make sense of it.
Does anyone here have these meters and can explain this? is there a quick way to zeroize the relative value setting?
