BESTNEW-07 digital display is a multi-functional sensor signal display, which can cooperate with resistance strain type weighing force / potentiometer type displacement sensor and LVDT type sensor. It has the convenience of all-digital calibration and high-precision display practicability. It can optionally be equipped with setting value control interface / analog output interface / RS-485 digital output interface. Can be widely used in various scientific research and industrial control occasions.

Main performance:

Accuracy: 0.01% F. S

* Fixed value control points: 4 (can be selected as ordinary fixed value and selection function)

* Analog output: 12 bits 4 ~ 20mA 0 ~ 5v / 10v optional.

* Digital output: RS-485 baud rate is optional.

Shape: 80 × 160 × 130

Power supply: AC 220V

connection:

BESTNEW-007's rear panel is used to connect sensors and power and other output devices:

E +: Connect to the positive terminal of the power supply of the load cell. For displacement sensors, it is the negative terminal of the power supply.

E-: Connect the negative terminal of the power supply of the load cell. For displacement sensors, it is the positive terminal of the power supply.

IN +: Connect to the positive output terminal of the load cell. For the LVDT sensor, it is the negative terminal of the output signal.

IN-: Connect to the negative terminal of the signal output of the load cell. For the LVDT sensor, it is the positive terminal of the output signal. For potentiometer sensors, this is the signal output of the sensor.

16: Analog output positive terminal

17: Analog output negative terminal.

1: RS-485 output A

2: RS-485 output B.

1 # 2 # 3 # 4 # are 4 output terminals of setting control relay. (Specify normally closed / closed when ordering)

AC 220V AC power input (DC 24V input)

Front panel:

The front panel of the BESTNEW-007 digital display has 6 LED digital tubes and indicators and 4 buttons. Six digital tubes are used to display measurement data and set parameters. The indicator shows the working status. 4 keys are used for function operation and data input.

Zeroing: Use the current data as the zero reference.

Mode: Used to set the set control value.

Shift: Used to select the position of the set value when entering data.

Set number: Enter the appropriate data with the shift key.

operating:

The BESTNEW-007 digital display must be properly connected to the sensor before powering it on. Otherwise, the display will show an error when powering on.

Press and hold the zero key for 2 seconds, the current displayed value is set to zero.

Press the mode key. The display shows: setup At this time, press the shift key to enter the set value setting state. The display shows: 1XXXXX

At this time, use the shift and set keys to input the required value, and press the mode key to end. The display shows: 2XXXXXX, also use the shift and set keys to enter the required data, and press the mode key to enter the next step. . . . . . . . When there is no need to modify the setting data, directly press the mode key until it returns to the normal display state.

Note: set value 1 <set value 2 <set value 3 <set value 4

Correction:

The calibration of BESTNEW-007 digital display requires the following operations:

In the off state, press and hold the zero key to turn on the power. After the monitor self-tests, press the mode key. The display shows: CAL SP. Press the shift key to enter the calibration routine. Otherwise, press the mode key.

The display shows: SET Press the shift key to enter the basic parameter setting program,

Otherwise, press the mode key to display the display: A / D Press the shift key to enter the state of displaying the A / D conversion internal code.

Press the mode key. The display shows: d / A Press the shift key to enter the analog output setting.

Before performing the calibration, the basic parameters should be set:

After entering the basic parameter setting program, the display shows: d xx n is the division value (resolution). Use the set key to select the appropriate division value and confirm with the mode key. After confirmation, the display shows: n xxxx indicates the division number (display accuracy, Division value × division value = display range), you can use the shift and set keys to enter a new division number. After confirming the number of divisions, press the mode key. The display shows: FLt xx enters the filter parameter setting. You can use the shift and set keys to enter new parameters. The small value shows fast response. Press the mode key to display: b xxxx can set the baud rate of the RS-485 interface at this time. After setting, press the mode key to return to the normal display state.

After entering the calibration process, the display shows: CAL 00 enters the zero calibration, press the mode key after confirming the zero position, the display shows ------ a few seconds after the maximum measurement value XXXXX is displayed, and the measurement value is loaded (if it cannot be loaded to the maximum measurement value Enter the new load value with the shift and set keys), and press the mode key to confirm after loading. After a few seconds, the calibration will return to the normal display.

After calibration, the power must be turned off and then turned on again for normal use.

Adjustment of analog output:

After entering the analog output setting program, the display shows: dA XXX indicates the analog output zero position, press the set key to increase the analog output value, press the shift key to decrease the analog output value, and press the mode key to confirm when adjusted to the required value. The display shows: FU XXX enters the analog output full-scale adjustment. Press the set key to increase the output value. Press the shift key to decrease the output value. When the desired value is reached, press the mode key to end the adjustment.
