Frequently asked questions
How is the GBB-3001 calibrated?
The GBB-3001 is calibrated externally with a reference weight of known mass. Globe also sells it as the GBB-3001-CT, which includes an ISO/IEC 17025:2017 accredited calibration certificate.
How big is the GBB-3001’s weighing pan, and how fast does it settle?
The pan is 145 x 145 mm and Globe rates stabilization at 3 sec. The balance itself measures 225 x 177 x 157 mm.
Can the GBB-3001 run without mains power?
Yes. It runs on the supplied 9 V AC adapter or on six AA batteries (not included).
What do the GBB-3001’s repeatability and linearity figures mean?
Repeatability of 0.1 g is how closely repeated weighings of the same load agree. Linearity of 0.2 g is the largest deviation from the true mass across the weighing range. Both are Globe’s specifications for the GBB-3001.
