CALIBRATION
Always warm up the scale before calibration. Always calibrate your scale before use. This
must be done WITHOUT the powder pan on the platform. To calibrate the scale, follow the
steps below:
Step 1. Be sure the powder pan has been removed from the scale platen. When you turn
the scale on, the display will show 99999 across the display for a few seconds and then
counts down to display 0.0 GN (grains mode). Once "Stable" shows up, the scale is ready to
proceed with calibrating. See Fig. 1.
Step 2. Next please press [CAL] key on the scale. The display will show C 0, with a lower
case g in the upper right hand corner of the display. See Fig. 2.
Step 3. When the display shows C 0 and "Stable" shows up, press the [CAL] key again.
Step 4. When the display shows C 50, place a 50 gram weight on the platen and press the
[CAL] key. See Fig. 3.
Step 5. When the display shows C 100, add the second 50 gram weight to the platen and
press the [CAL] key. See Fig. 4.
Step 6. Now the display will show 100.00 g, See Fig. 5. Remove both weights from the
platen, and replace them to their weight holders. The display will automatically switch to
0.0 GN (grains) and the scale will sound a beep.
Step 7. Next place the powder pan on the platen and press the [ZERO] key to zero the
weight of the pan. The display will show 0.0 GN and is now calibrated and ready to
operate. See Fig. 6.
Notice: In the calibration process, when it shows ERROR, it is probably caused by the
incorrect weight. Please use the weights we provided.
