The panel meter is designed for use with strain gauges and load cells. Programmable function keys make operation easy.
Multi-purpose and easy-to-use, this digital panel meter is ideal for weight and force measurement applications. Additionally, this meter features a maximum current of 350 mA at 10 V and can support up to twelve 350 Ω load cells.
Features
Precise, accurate, and informative
This panel meter's large 0.6" (11.68 mm) upper display provides a highly accurate and precise 6-digit view of the process measurement. Its 24-bit A/D is accurate to ±0.03% of calibrated span ±1 count.
Configurable
The upper display can be programmed to indicate PV, maximum (peak), minimum (valley), alternating maximum/minimum, one of eight alarm set points, or Modbus input. The lower display can also be configured to display engineering units, set points, user defined legends, or simply turned off.
SunBright LED display
This panel meter's SunBright display features extraordinarily bright LED displays. It is perfect for outdoor applications where visibility may be impaired by smoke, fog, dust, or distance. The intensity on the SunBright display is so high it can be read even in the brightest sunlight
Function keys
There are three function keys available to the user. These keys can be programmed to trigger certain events (i.e. acknowledge alarms, reset maximum and/or minimum, disable/enable output relays, or hold current relay states), provide direct menu access points, and more.
Free USB programming software and cable
This panel meter comes preloaded with free MeterView® Pro programming software that connects and installs directly to your PC with a standard USB cable. This eliminates the need to insert CDs, install drivers, or download software from the internet. The software will allow you to configure, monitor, and datalog a panel meter using your PC. Just simply connect the meter to your PC with the USB cable and within minutes you will be programming it.
Rugged
A unique front panel design makes the panel meter nearly impenetrable in typical applications. Here, the panel meter easily survives a direct hit on the display from a heavy 2" (5.08 cm) solid stainless steel ball dropped from a height of 8' (2.4 m).
On-board digital input
This panel meter includes a digital input as a standard feature. This digital input can operate with the tare, reset tare, or interlock relays feature, force relays on from a signal from a PLC or relay on other equipment, and much more. This is ideal for installations where the meter is inaccessible behind a cover, or where an additional function key is needed for customized operation.
Zero the meter
The zero function zeroes out the display. In the case where there has been drift in the strain gauge output over time, zero is used to eliminate this drift and provide a true zero reading. For example, if an empty scale were to display a value other than zero, the zero function would tell the meter to show zero regardless of the current input signal.
Capture tare
The tare function also zeroes out the display. In the case of scale weight, tare is used to eliminate container weight and provide net weight readings. If the tare value is a known constant, such as a container weight, this may be programmed in manually. The captured tare may be reset manually with any function key or digital input.
Automatic unit conversion
In addition to entering a custom unit or tag, pre-defined engineering units may be selected: lbs, kg, ounce, gram, ton (short), tonne (metric ton). Automatic unit conversions are done when switching between pre-defined units, without the need for additional scaling. The meter converts the reading according to the unit selected (e.g. 100.00 lbs = 45.36 kg = 45359.2 g = 1600 oz).
Auto-zero
The auto-zero feature corrects for drift that can occur over time that causes the input signal to slowly change. The meter will continue to read zero despite slow and small changes to the input signal around zero. The auto-zero sensitivity is set by the user as a percent of full scale.
Rounding
The rounding feature is used to give the user a steadier display with fluctuating signals. It causes the display to round to the nearest value according to the rounding value selected (1, 2, 5, 10, 20, 50, or 100). For example, with a rounding value of 10, and a input of 12346, the display would indicate 12350.
Shunt calibration check
This panel meter is equipped with a means of simulating strain in a strain gauge bridge circuit, via an included shunt resistor in the meter. This technique can be used as a means of verifying the meter setup and output behavior by simulating a physical input. With no load connected, the enabling of the shunt resistor will simulate a 70% full scale load in the case of a 350 Ω Strain Bridge.
Ratiometric compensation
This feature compensates for changes in the strain gauge input signal that are due to variations in the internal or external excitation voltage. The compensation is effective for up to ±5% variation in the excitation power supply.
Dual-scale display feature
This panel meter has a rather unique, and very flexible dual-scale capability; a second scaled display can represent the measured input in a different form (i.e. gallons and height). This is of particular value in level applications. Both displays are independently scaled and are based on the 4 to 20 mA input signal. Beyond level, this function has been used for pressure and force, weight and piece count, feet and meters, and more.
Advanced linearization capability
This panel meter includes a 32-point linearizer. In non-linear level applications (i.e. some pumping or lift stations), it can easily compensate for submerged equipment or plumbing that displace usable volume. The free MeterView Pro PC-based software greatly simplifies the construction of the linearization tables. The software can save this data to the meter and/or PC.
