2.7 Setting the Validator AVS Time and Date
When the Console starts any kind of study, the current time and date are automatically
transferred to the attached Validator AVS. No action on your part is required. Refer to the
Windows documentation for instructions for changing the date and time.
2.8 Preventive Maintenance
2.8.1 Fuse Replacement
The Validator AVS is equipped with a 250V T 4A fuse. The fuse is located in the line filter
along with the power cord. To replace the fuse:
1. Turn the power off.
2. Disconnect the power cord from the line filter.
3. Using a small, slotted screwdriver (provided with the SIMs), pry open the fuse
holder from the bottom tab.
4. Slide the fuse holder out and replace the fuse with a 250V T 4A replacement fuse.
2.8.2 Calibration
Each Validator AVS is fully calibrated before shipment. The equipment normally requires
no further adjustment or calibration during installation. Under normal operating conditions,
it is recommended you calibrate the Validator AVS once a year to maintain peak system
accuracy. If you use a Validator AVS for high accuracy measurements, or if circuit boards
are replaced or added, you may need to certify the calibration more often.
