CALIBRATION SEAL INSTALLATION

If your 220 Weight Indicating Instrument is used in a commercial application it must be tested and
sealed by your local weights and measurements official. The 220 is designed to accept a lead and
wire security seal to prevent unauthorized access to the calibration adjustments. Refer to the
Figure No. 9 for details on the installation of these seals.
