:: Frequently Asked Questions ::

Q: What is accuracy?

Closness of agreement between a measured quantity value and a true quantity value of a measurand.

Q: How far does RS-232 travel?

Because of sensitivity to noise, RS232 is not recommended for applications requiring more than 15 meters of travel.

Q: Which would travel farther in RS-232, 9600 or 1200 baud?

In this case 1200 baud. In general, slower baud rates will travel greater distances.

Q: What is bagging scale?

Bagging scales are used all over the world in grain, sugar, rice and fertilizer silos, mills and all branches of industry in which bulk commodities are bagged. In seaport silos, for example, sugar may need to be bagged if the destination port is not equipped to unload bulk commodities.

Q: What is bridge scale?

General name for scales in which the suspension (support elements) of the load receptor is arranged underneath and hence loading is not hindered by any suspension devices installed above the load receptor. This constructional form of the load receptor is called a bridge scale, and this type of load receptor a weighbridge. The weighing platform rests on several elements that are connected by joints (not necessarily lying in a horizontal plane) that have linked levers, as for example in the decimal balance. The weighbridge can also rest directly on multiple load cells (road vehicle scale). Heavy-duty scales are often assembled from multi-part linked weighing platforms.

Q: What is handshaking?

In the case of scale related equipment, it's a method of slowing, stopping and starting the flow of data between two independent devices.

Q: What can cause a voltage spike?

Power surges can have many sources. Introduction of lightning into a power line, communication line, signal or sensing line, and even ground line is an obvious reason. Surges could also be related to a local power company or load issue in your area. Also look for other large equipment sharing your power source. As it switches on and off, power surges are also quite common.

Q: What is load cell?

Electromechanical measurement transducer for determining mass, in which the weight force exerted by the weighed object is converted into an electrical signal.

Q: What is conveyor belt weigher?

Scale that determines the weight of unpacked, loose, continuously transported material by weighing the belt loading and measuring the belt speed while the material is being transported (integrated scale). Conveyor belt weighers can also be designed as adding scales that weigh the material in sections.

Q: What are the differences between LED, LCD, and VFD displays?

Light Emitting Diode (LED) and Vacuum Fluorescent Display (VFD) display types are recommended for indoor applications, identifiable by digits that light up over a dark background. Exceptions like our Laserlight series (an LED type display) are designed for viewing outdoors. For most applications in sunlight we suggest a Liquid Crystal Display (LCD), which is identifiable by black digits over a gray (or backlit) background.

Q: What is bench scale?

A scale with a weighing capacity of up to approximately 30 kg that is used on counters, benches, or tables,...

Q: What can I use to help with power problems at my input?

It is always a good idea to use something like a power strip/Isobar or surge protector at a power source. But if these aren't enough, consider using an Uninterruptible Power Supply (UPS) to help ensure consistent current flow to your equipment.

Q: What is crane scale?

scale used to weigh the load suspended from a crane. The scale can either be suspended from the crane hook or integrated in the structure of the crane. In the latter case the cable drum and drive, as well as all cable guide parts, are part of the scale preload.

Q: What are the main devices of the weighing instrument?

Depending on the model, a mechanical weighing instrument is composed of load receptor (parallel guide), load transmitter (hanger, lever system), and the display device. In addition, an electromechanical weighing instrument has a measurement converter, at least one signal processing unit, and possibly a device for transmission of results (data transmission).

Q: What is TTL and what is it used for?

Transistor Transistor Logic simply refers to digital outputs/inputs that use simple 5 volt logic, meaning they are either 0 or 5 volts in their on/off states.

Q: What is hopper scale?

Scale for hoppers, usually with load cells in tension or compression between each of the hopper supports and an overhead structure or foundation, for weighing or apportioning free-flowing bulk materials.

Q: What is maximum capacity?

Upper limit Max of the weighing range without consideration of an additional maximum tare, i.e. the maximum capacity whose weight can be determined on a balance

Q: What is maximum safe load?

Largest static load limit Lim that can be carried by a weighing instrument without permanently altering its metrological properties, and without the risk of damage, but which cannot usually be measured. It is always greater than or equal to the maximum capacity plus the additive maximum tare effect.

Q: What is platform scale?

Bridge scale for industrial use with flat load receptor (floor scale, low-profile scale) and usually ground-level bridge surface
