| Search Logic: | All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches. | ||
| Scale Length | The scale length of the panel meter. | ||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
Inputs

|
|
| ||
| Analog Input Channels: | Number of all analog input channels. This includes both general & specific types. | ||
| Search Logic: | All matching products will have a value greater than or equal to the specified value. | ||
| Voltage Range | The range of voltages the meter is capable of measuring. | ||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
| Current Range | The range of currents the meter is capable of measuring. | ||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
| Frequency Range | The range of frequencies the meter is capable of measuring. | ||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
| Analog Input Type | |||
| Your choices are... | |||
| AC Voltage | Input is received as a measurable form of AC voltage. | ||
| DC Voltage | Input is received as a measurable form of DC voltage. | ||
| AC Current | The input is designed to receive AC current. | ||
| DC Current | The input is designed to receive DC current. | ||
| Frequency | The input is designed to receive a frequency or pulse. | ||
| Single Phase AC Power | Input is received as an adjustable range of single phase AC current, voltage and/or frequency. | ||
| Three Phase AC Power | Input is received as an adjustable range of three phase AC current, voltage and/or frequency. | ||
| DC Power | Input is received as an adjustable range of DC current, voltage and/or frequency. | ||
| Strain Gauge | A strain gauge is a sensing device, attached along its entire length to a surface so that its resistance will change as the surface is deformed. Strain gages are typically used as elements in a Wheatstone bridge circuit, which is used to make the measurement. | ||
| Resistance | Piezoresistive sensors are based on semiconductor technology. The resistance changes because of alterations in the length and width (as with strain gauges) as well as a shift of electrical charges within the resistor. | ||
| Temperature | Thermocouple (TC), RTD or thermistor input accepted. | ||
| Other | Other unlisted type of input. | ||
| Search Logic: | All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches. | ||
Outputs

|
| ||
| Output Type | |||
| Your choices are... | |||
| Analog | Analog outputs are used in applications that require digitally controlled output voltages usually within the range of +/-10 V or less, and at current levels below 10 mA. The heart of an analog output channel is a digital-to-analog converter (DAC), which converts a digital code into a voltage level. The output of the DAC is then processed or conditioned to produce the required output signal characteristics. | ||
| Parallel | A channel capable of transferring more than one bit at a simultaneously. | ||
| Serial | A port, or interface, that can be used for serial communication, in which only one bit is transferred at a time. | ||
| Relay | One of the most common types of outputs available is the relay output. A relay can be used with both AC and DC loads. | ||
| Other | Other unlisted type of output. | ||
| Search Logic: | All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches. | ||

|
|
| ||
| Features | |||
| Your choices are... | |||
| Adjustable Display | The meter can be adjusted to show different displays. | ||
| Alarms | The meter has alarms to indicate when limits or set points are reached. | ||
| Displays Bargraph | The panel meter also has an integral bar graph display in addition to the main display. | ||
| Displays Digits | The meter also has a digital display. | ||
| Intrinsically Safe | At facilities where there are flammable or explosive materials, operating at low energy can prevent electrical devices from creating arcs, sparks, or heat (during normal or fault conditions) that could ignite the explosive substance. Such a system is termed "intrinsically safe." | ||
| On / Off Control | The meter has the ability to turn the input sensor or transducer on or off. | ||
| Also a Scanner | Meter has the ability to scan or multiplex. | ||
| Set Point Options | Ability to set points in the display that the data must be displayed between. | ||
| Signal Conditioning Ability | Meter has the ability to condition the signal upon receiving it. | ||
| Totalizer | A totalizer counts and records the data for a set or indefinite period of time. | ||
