Sealing And Audit Trails
Most legal-for-trade installations will require the Model 350/355 to be sealed. A sealed indicator cannot be accessed for
setup or calibration changes without breaking a physical seal or incrementing an event counter, thus providing evidence
of tampering.
The Model 350/355 has two types of sealing provisions, a physical seal and a three event audit trail counter. Check
with your local weights and measures authority to determine your requirements.

The most common sealing method is a lead-wire seal. The Model 350 and Model 355 provide an easy means of
applying this type of seal as shown in Figure 38.
Before applying a wire seal, move the program jumper to the ‘NO’ position as shown in Figure 37. This will prevent
access to the Setup and Calibration Modes.
