FAQsFAQs
Q: How do I clean a touch screen?
A: Any standard glass cleaner can be used to clean the touchscreen, but avoid products containing ammonia.
Always spray the glass cleaner on the cloth or towel and then clean the touchscreen.
Glass cleaner sprayed directly on the monitor could possibly leak inside a non-sealed unit and cause damage.
Q. How long would my order take to arrive?
A. Lead-times are typically about 4 days (mainland UK) but can be longer for large orders or if items are out of stock. You will be advised of the expected lead-time for your goods prior to placing an order. We strive hard to be flexible and helpful so if you have urgent orders please speak to us, and if it is at all possible to meet your deadline, we will.
Q. What warranty do I get?
A. All our products come with a 12 month limited warranty, return to base, including parts and labour. Warranty upgrades can be purchased.
Q. What does the IP rating mean?
A. IP Rating is an industry standard system for classifying the degree of protection provided by the case of an electrical item.
The first number indicates the extent to which the product is dustproof and the second number the extent to which the product is waterproof. The higher the rating the higher the protection.
IP43 = Protected against solid objects over 1mm,and protected against direct sprays of water up to 60° from the vertical.
IP64 = Completely dustproof, and protected from water splashing in any direction.
IP65 = Completely dust proof, and water projected in jets against the enclosure from any direction shall have no harmful effects.

Q. What is the difference between Resistive, Capacitive, and SAW touch-screens?
A. There are several different types of touch-screen technology available. Our Vand product range makes use of three of the most popular types: resistive, capacitive and SAW. On some of our ranges you will be asked which type you want. Each touch technology has its own inherent advantages and disadvantages and therefore it will depend on your application and environment as to which one is best for you.
Resistive
Resistive is the most popular type of touch-screen technology and is commonly used in EPOS systems, medical systems and industrial panels. It generally uses a display overlay composed of layers, each with a conductive coating on the interior surface. When it is touched the layers make electrical contact at that point.
Resistive touch-screens therefore have the advantage that they can be operated with any input device, including a gloved hand or stylus. They are also relatively cost effective. However, resistive screens can be damaged by sharp objects and because they have an overlay they offer only about 75% screen clarity, which whilst acceptable for most applications may create problems for people with low vision.
Capacitive
Capacitive touch-screens offer higher clarity and are more durable, but they do not respond to gloved hands or most styluses. They work by using oscillator circuits that are located in each corner of the glass overlay and measure the capacitance. Depending on where the person touches the overlay, the oscillators will vary in frequency.
Surface Accoustic Wave (SAW)
Surface acoustic wave (SAW), both provides high clarity and durability and can be operated by either human touch or stylus. When sound waves are transmitted across the surface of the display, each wave is spread across the screen by bouncing off reflector arrays along the edges of the overlay. Two receivers detect the waves. When the user touches the glass surface, the user's finger absorbs some of the energy of the acoustic wave and the controller circuitry measures the touch location.
This technology, however, cannot be gasket sealed so is unsuitable in harsh industrial environments that require wash-down, and is also currently much more expensive than resistive or capacitive touch-screens.
