accuracy.
1. Place 5.00 kg (15.00 lb.) of weight in position 1 on the Top Plate.
2. Move the weight to position 2 on the Top Plate. The display should show 5.00 ± 0.005 kg
(15.00 ± 0.01 lb.).
3. Repeat step 2 for positions 3, 4, and 5.
4. Move the weight to position 1 again.

Secure the Calibration Switch
Remove the Top Plate. Rotate the Calibration Switch Security Cover into position and install the
screw.
When you perform a scale calibration, someone must seal the Calibration Switch Security Cover.
This may be done with a Lead/Wire Seal (NCR part number 603-8001097) using a Lead/Wire
Seal Press (NCR part number 603-9000157) or a Film/Paper seal (obtained locally). The type of
seal you use depends on your local laws; also, Weights and Measures officials may be required
to attach the seal.
NOTE: In the United States and Canada, the audit trail can serve as an acceptable security seal
if an NCR 7825 Display is used as the weight display.
After securing the Calibration Switch, if the unit is a RealScan 7875-2000, install the plastic
Calibration Switch Cover and the Produce Guard if included. Install the Top Plate.
