e (Verification Scale Division)

The smallest division (interval) a scale may have and be permitted to set price based on weight

E-min(minimum verification scale division)

Smallest division permissible for a scale to still be able to set price based on weight

Eccentric Load

A load which is non-symmetric with the central axis of a support system. In the case of scales, a base which is not level will create error due to eccentric loading.

Electrical Noise

Unwanted electrical signals which distort or interfere with the desired signals

Electrical Safety Analyzer

A device dedicated to a various range of electrical safety tests in order to check that the device under test is in compliance with electrical safety requirements

Electromagnetic Interference (EMI)

A disturbance generated by an external source that affects an electrical circuit by electromagnetic induction, electrostatic coupling, or conduction.

Electromotive Force (EMF)

Abbreviated EMF, is the electrical intensity or developed by a source of electrical energy such as a battery or generator. A device that converts other forms of energy into electrical energy provides an emf as its output.

Electrostatic

Relating to stationary or slow-moving electric charges rather than currents.

Electrostatic Charge

The excess or deficiency of electrons on a surface which gives the surface a certain positive or negative charge

Electrostatic Discharge

A flow of electricity which causes an object to lose some or all of its charge.

Endothermic

Accompanied by or requiring the absorption of heat (as in a process or or reaction).

Environmentally Protected

There are legislation and or practices in place to protect that area or species

Environmental Testing

Also referred to as climate testing, environmental testing subjects products to induced environmental conditions to evaluate the effects of these conditions on the product. These conditions may include temperature, humidity, precipitation, radiation, pressure, corrosive elements, etc.

Error (Measurement)

The difference between the actual value and the measured value

Eutectic Temperature

The lowest melting point of a temperature system, usually two or more metals; often characterized as a bonding point, as in eutectic bonding gold to aluminum silicon.

Excitation

The application of energy to a particle, object, or physical system. In load cells and other strain gauge systems, an excitation voltage is applied to energize the bridge circuit.

Excitation Trim

The oldest and still most used method of trimming each individual load cell in a scale or similar system with multiple load cells. The output is trimmed by placing series resistance into the supply circuit to reduce the excitation voltage, resulting in the reduction in sensitivity of the individual load cells to equal the lowest one.

Expanded Scale

An arrangement that expands a specific portion of an overall range to occupy a larger portion of the full-scale length than it normally would.

Explosion Proof

Explosion-proof equipment serves a crucial role in safeguarding environments where the potential of explosions exist. Read More…

Eyepiece Graticule

A glass disc fitted into the eyepiece of a microscope. These can be fitted to existing eyepieces or eyepieces can be purchased with graticules already fitted. The disc is marked with a fine scale from 0 to 100.

Did you know… Cross Company is an ESOP (Employee Stock Ownership Plan). Our ESOP started in 1979 and as of 2006, we are 100% employee-owned! Learn more about our ESOP and how that benefits both team members and our customers.
Did you know... the precision measurement group at Cross was founded in 1939 by our current CEO's grandfather, Jim King. That's a whole lot of calibration!
Did you know... A fingerprint weighs about 50 micrograms. We know, we weighed it! The residue left from a finger can actually make a difference in weight results which is why we wear gloves when we calibrate weights. For reference, a sheet of paper is about 4.5 grams, that’s 4.5 million micrograms.
Did you know… Cross Company has grown significantly since our start in 1954. Over the years we've acquired 26 companies! Today, our five groups have expertise in everything from industrial automation to precision measurement, and industry knowledge going all the way back to 1939.
