Analog Clock Hand Calibration Procedure
Previous

The analog clock hands have been pre-set and aligned at the factory. This hand location and alignment information is retained in non-volatile flash. Under normal operating circumstances it is not necessary to adjust or align the hands of the analog clock. However, if for any reason, the hands are not tracking the NTP source, an adjustment function has been built into the analog clock and its support software. The 'Calibrate Analog Clock" button, in WinDiscovery, allows the user to fine tune or re-calibrate the hands of the clock.

[Note: for the purpose of maintaining its internal clock, the network clock always assumes the time entered is UTC and saves this information as the internal UTC time. Any configured time zone/daylight time settings will then be applied to this UTC time to obtain its local time. For time display purposes, the network clock references it's internal local time]

 

[Important Note: DO NOT ATTEMPT TO SET THE TIME of the clock using the following calibration procedure. This procedure is a calibration procedure only, used to fine-tune the hands. This clock will self adjust to the UTC time reference provided by the NTP time server, plus any Time Zone and DST offset settings that have been configured [i.e. to internal local time]. To configure the time displayed on the face of the clock , refer to the appropriate sections of the user manual for configuring the IP address, NTP time server(s), Time Zone, and DST settings.]

[Note: The visual determination of the accuracy of the hand display should be done by comparing the clock hands only after the analog clock indicates that it is synchronized to an NTP server, and then only to a digital display, from an accurate locked NTP server or synchronized digital display clock placed next to the analog clock.]

To calibrate the hands: [Note: you must be viewing the actual face of the clock to perform this function. Do not use the status indicator under WinDiscovery to “view” the clock face.]

Press the “Set Analog Clock Hands” button to enter the adjustment mode, the hands of the analog clock will stop. Select the “Check to set clock” box. Enter the correct hour, minute, and second currently exactly as displayed on the face of the clock. If the second hand is not currently aligned on a second mark, you can nudge the second hand forward incrementally using the “Forward” button. Select the OK button to accept the new settings. The new hand alignment settings will be stored in non-volatile flash. The clock hands will adjust to the new settings and will continue displaying the time after several moments. [Note: it is suggested to double check the new settings with the digital display reference at this point to ensure that the hands have been correctly set]


Warning, do not use this procedure to set the time on the analog clock. Only enter the current time as displayed on the face of the clock (the current hand position), when the hands are stopped.
