When used, the voltage across the reference resistor can be directed to the voltmeter using the multiplexer followed by a measurement of the voltage across. The two measurements can then Agilent 34923A used to calculate.

Compromises Using the 3-Wire Technique To reduce measurement cost, as compared to the 4-wire Agilent 34923A, it is possible Agilent 34923A use a 3-wire configuration as shown in Figure 5. Older test instruments used Wheatstone bridge input circuits, dedicated to measuring 3-wire devices. Modern DMMs such as the one built-in the A are not limited by the older circuit design and offer the more accurate 4-wire measurements.

While 3-wire resistance measurements do not compensate as well as the 4-wire technique, measurement accuracy is better than with the 2-wire measurement. These sensors are Agilent 34923A measured with the 3-wire technique because they are 3-wire devices.

Agilent 34923A A DMM supports both curves. Today, because of the low resistance and desire to maximize accuracy, a 4-wire technique is most often used.

Note that additional accuracy can be achieved by using the Callendar-an Dusen equation to further correct for non-linearity. See Practical Temperature Measurements Application Note literature number E Agilent 34923A more details and for thermocouple and thermistor temperature measurement details.

The voltage drop across each can be measured through a multiplexer. This is a pseudo 4-wire system where resistance errors due to the multiplexer relays and associated leads are Agilent 34923A. Consider Resistance from Relay Contacts At first glance, an electromechanical or amature relay seems to be a fairly simple device where the closed contact resistance is assumed to be insignificant.

The reality, however, is that contact resistance is Agilent 34923A on and can change due to current, the number of relay actuations and age. Agilent 34923A

Agilent 34923A The nature of the problem can be appreciated by considering that relays operate by pulling together a set of metal contacts that are contained in some type of case. The materials of construction and Agilent 34923A nature of the environment drive the quality of the electrical contact, as shown in Figure 8.

While the materials used for relay contacts have substantially advanced, there are still tradeoffs that effect relay performance. Common concerns with the relay contacts are fretting, oxidation, contamination and electromigration. Fretting is the removal Agilent 34923A materials due to the repeated closure of contacts. It is essentially a wear out mechanism that leads to surface asperities and pitting.

The change in profile limits contact areas and increases resistance. Oxidation of the Agilent 34923A can also occur.

Since oxides are typically poor conductors, this also leads to increased resistance. Sales Tax: Charged Agilent 34923A all California Purchases unless a valid tax exemption certificate is provided. Payment must be received within 7 days.
