Product Detail: |
The DigiTec D3700A series digital panel meters are available as either the single-channel D3720A or the dual-channel D3722A. These full-featured meters include a 6-digit LED display, a user-friendly configuration menu and high-speed measurement rate for the most demanding applications. Combine all of this with its clean appearance, industrialized aluminum case, NEMA 4X construction and snap-action buttons and you have a meter ready for all applications.
3 Types of Calibration:
USER - calibration allows the entry of the low and high input values and the corresponding low and high display engineering values.
LOAD - calibration allows setup via known input values. Simply apply the low input and set its corresponding display value, then apply the high input and set its value. The low and high values can be programmed at different times and then enabled.
SHUNT - calibration allows setup via an external shunt calibrator resistor. Simply set the display low value and the shunt cal display value, then the meter will automatically measure the unloaded bridge for the zero value; then closes the
internal shunt cal relay and measures the shunt calibrated input.
Autotare: This function allows the user to set the selected display/input to zero. It can be performed via a front panel key or remote input. Setup is available to switch the display from net to gross.
Net/Gross: The net value or the gross value can be displayed via a front panel key or remote input. Alarm limits, analog out or peak values may be assigned to the net or gross values.
Lineariation: U-plot 20-point linearization allows the user to program up to 20 known values of non-linear curvature along with the corresponding display readings. Typical uses are for non-linear outputs from transducers, load cells, etc. and for display of volume in non-linear storage vessels.
Math Channel: The D3700A series comes with an extra channel that is a non input channel. This can be used to duplicate an input channel for completely new scaling and alarm setups. The two channel input model D3722A can be used to perform A + B, A – B or A ÷ B math functions. (Consult ATC DigiTec for your special equations)
Second Scale: This function allows the user to set a second scaling to the input. The input will then be displayed in two engineering units (typically for English/Metric displays).
Peak 1 and Peak 2: Peak 1 and peak 2 are both assignable to capture the maximum or minimum display value. They are assignable to any channel and the net or gross value. It can be reset through a front panel key or remote input. Capture rate is 20/sec.
Programmable Lockout Code: A 2-digit code -0 -50, for set-up is programmable. Setup can also be protected via a remote input.
Digital Filter: This function allows the user to select a digital filter. This is used for noisy, unstable inputs.
Alarms: Each meter is standard with 4 programmable alarms that control the front panel LED status and the one standard relay (Form A) and optional 3 relay outputs (Form C). Each alarm is:
• Alternate Hi/Low on alarm 1 & 2
• Assignable to any channel
• Programmable for High or Low limit
• Programmable setpoint value
• Programmable hysteresis for complete display range
• Programmable for latching
• Programmable to Flash Display on alarm
• Alarm #1 is programmable for fail safe operation for all the alarms. (Fail safe operation allows the relay to de-energize
on loss of power.
Non-volatile Memory: All setup data entered by the user is stored in a non-volatile memory. No batteries needed and no need to re-program the meter after power down.
Relay Output: 1 Form "A relay 240VAC @ 1A, is provided standard for use as an alarm output or Shunt Cal relay.
Display: 6 Digit .56" Red LED display for readings of
-19999 to 999999 with selectable decimal points.
Input: Process inputs of plus and minus inputs of 30mV, 100mV, 200mV, 2V and 10V. 20mA input is solder selectable on main board. Display and outputs are updated at selected resolution.
Display Update: 30/sec fixed.
Excitation: Optional, 10VDC @ 250mA, 24 VDC @ 150mA. Consult factory for 5 VDC @ 100mA. |
