Which exam clock should I buy?
The Exams Office recommends clocks with HH:MM:SS for accuracy in the exam room. However, clocks that display HH:MM can also be used in the exam room. The viewing range will depend on your exam room. A 25m range will suffice for classrooms. But a 50m range will be required for sports hall to ensure that you comply with JCQ regulations which state that “A reliable clock (analogue or digital) must be visible to each candidate in the examination room. The clock must be big enough for all candidates to read clearly”.
Do you have smaller/larger clocks?
As well as our exam clocks, we also offer a range of clocks which can be used across your school/college for other academic and general purposes.
Do you offer battery powered clocks?
We do not currently offer battery powered clocks. The exam range of Wharton clocks is provided with a long 5m mains power cable. We can offer as an alternative PoE (Power over Ethernet) clocks which can be powered and synchronised via a single network cable when connected to a suitable PoE network switch.
Do I need to set up my digital clock? Will I have to set up the clock every time I need it?
Our clocks are pre-configured with factory defaults that should suffice your needs. The high quality quartz oscillator keeps the clock to an accuracy of 0.1 sec/day, and an internal battery inside the clock keeps time running when the unit is not connected to mains power.
All settings applied to the clock remain during periods of disconnection, so there’s no need to set up the clock every time it is needed, unless you want to use a different countdown clock configuration each time.
How do I set up my digital clock?
Every clock comes with an instructions manual which will allow you to set up all aspects of your clock.

How long does the battery last?
Our clocks are designed for constant operation. The internal battery will keep time for up to 1 year if disconnected from power supply. After that, it can be easily replaced with a standard CR2032 3V battery.
How do I mount the clock?
There are two brackets attached to the back of the clock which pair to the wall brackets provided with the unit.
Fix the wall brackets to the surface and hang the clock as in the following drawing.
The brackets allow to position the clock flat to the wall or at 3° or 6° angle.
The clock is also supplied with rubber feet to allow for it to be used on a desk or table.
Can I get extra wall mounting brackets to reposition the clock?
Extra brackets are available. Please contact us to place your order.
What else can I do with the clock?
** Connect it to an NTP server, PA system or GPS receiver via the pin connector located at the back of the clock for real time synchronisation.
** Connect it to a temperature sensor to display alternate time and temperature.
** Use as a time elapsed counter, either counting up or down, with any of the multiple configurations available.
Use the counter with the provided IR remote control or contact us for advanced options that can be connected to the back of the clock.
Are the clocks suitable for playgrounds and outdoors installation?
These clocks are designed for indoor use. We manufacture a range of clocks which are intended for use outdoors. Please contact us for a quotation.
Are they impact protected? Can I install the clock in a Sports hall?
If it is going to be installed in a sports hall, protecting your digital clock in a wire cage is a good idea, as the clocks are not prepared for impacts.
Please note all digital clocks are built to order, therefore they are non-returnable items
