This is not bad but I would like to calibrate amps at the lower end of scale. Is there a way to calibrate at 1ma? I am wanting to buy over 100 of these but this might be a issue. Please respond as soon as possibly.

With no load on the output the output current does not show zero amps. My application needs to have accuracy at low current levels.
Can you supply me with information that I can calibrate the output readings?

Hello Roberto,
Thanks for reply. Base on these information, please try the zero calibration.
Firstly, please press and hold the SET button without any load, then power the meter. When it displays main window, please release button. After that, zero calibration is finished.
Best regards. -
