Adjusting Tilt Stand

The U1251B digital multimeter comes with an adjustable tilt stand to free up your hands for day to day tasks. To adjust the meter to a hanging position, flip the stand upwards and over its maximum reach until it is detached from its hinge. Then flip the stand over so that the stand’s inner surface is facing the meter’s rear. Now, press the stand down into its hinge.

Does this come with a calibration certificate?

Yes- Certificate of Calibration will be available.
