EJ4100 compact scale runs on an AC adapter (included) or with 4 AA batteries (not included) making this the ideal school balance for the classroom or field use weighing. An easy to read LCD display with back light allows a quick reading of weight measurements at a glance.
Other features include:
* Percentage weighing and parts counting
* USB or RS-232 interface optional interface
* Full digital calibration
* Underhook weighing
* Specific Gravity function
* Check-weighing capability
* Fast - 1 second weighing results
* 5 year warranty
A key selling point of the EJ Series over A&D EKi Series is the digital scale operates on standard batteries that you can purchase in any store, while the EKi requires the purchase of A&D Weighing's expensive rechargeable NiMH battery pack.
The LCD backlight will turn on when the weight value changes more than 4d (4 x min. display division - 4 x 0.1g = 0.4g) or any key operation is done. When the weight data becomes and stays stable for some moment, the backlight will automatically turn off. There is also a setting that the backlight is always on or off.
The EJ digital scales can stack on top of another when not in use. Do not stack more than 3 units.
It is possible to have the Auto-power off function to switch the scale OFF, if zero is displayed for approximately 5 minutes.
The most common unit of weight used around the world is the gram, but there is often a need to shift to alternative units specific to the country where the digital scale is used or to select weighing applications such as counting or percent. It is possible to store only the units that will be actually used from the units available. It is also possible to specify the display unit that will be shown first when the power is switched ON.
The range for power-on zero is within ±10% of the weighing capacity around the calibrated zero point. If the power is switched ON while there is a load beyond this range, the balance will be tared to zero and the NET indicator and the ZERO indicator turn on.
Weighing equipment - The world runs on weights & measures. Almost everything you see & touch is weighed.
The entire EJ Series are "non-NTEP" while the EK-J are "NTEP Approved 6000d Class II Scales". If you are needing a scale for commercial weighing where goods are being bought or sold by weight none of the EJ Series are Legal for Trade and we recommend you consider either the EK-610J or EK-6100J
The optional EJ-12 hard shell transport case features die cut foam specifically designed for holding AND Weighing EK and EJ Series digital scales. This carrying scale is convenient for transporting the digital scale or just storing your scale when not in use to lessen the chance of damage to the precision measurement weigh sensor. Whether the scale is turned On or Off if one applies an excessive load or shocks the platform you can permanently damage any scale. The optional EJ-12 case is a low cost scale insurance policy to protect your scale.
What is a weighing underhook and how is the underhook installed and used with a digital electronic scale? We hope the video above will answer all those questions.
In the video above we show the EK6100J, with optional EKW-07i weigh below weighing underhook and the optional EJ-07 Underhook is installed on the EJ3000, EJ4100 or EJ6100 works in similar fashion. The underhook is installed on the bottom of the scale by removing the beneath weighing port cover and screwing the optional underhook assembly into the threaded mounting hole.
By attaching the underhook to the bottom of the scale, large objects that would be difficult to load on the weighing pan can be weighed. Also, since electronic scales are affected by temperate and magnetism sample being weighed that are hot, cold and magnetic items should always be weighed using the below weighing underhook.
In addition, the density (specific gravity) of objects may be calculate by weighing a sample in air and then in weighing the same sample submerge in water or other liquids.
