without calibration this little device is not much useful … is there any chance someone can write a readable calibration manual The calibration segment that exist in current user manual does not work!
What does ZERO, DIFF and VOLTAGE means?
How do I navigate trough table without it messing up with existing measurements?
I see that I can only edit ZERO and DIFF fields but I cannot edit VOLTAGE field. If the ZERO field defines when the active and gnd are connected, isn’t device smart enough to calculate the value?! If I short lead and gnd - it is zero ?! If the DIFF is difference between input voltage (coming from voltage source) and measured voltage, how to edit DIFF value when I don’t know what is measured by quad? Why not show the value in VOLTAGE while we are editing DIFF value so we can “make it same as input” - also, what is point of stepping on the VOLTAGE field if we cannot edit it ?!
This is serious part of the device, you really need to make this one work before you do anything else or this is then just another expensive unusable toy …
