220 Weight Indicator

1. Specifications:

★Simple comparison output method (this is the standard way)

Function description: The 3 outputs of the meter can be set to be more than comparison or less than comparison. The output is valid when the measured value is more than the upper limit minus hysteresis, and the output is invalid when the measured value is less than the upper limit. When the output is set to be less than the comparison, the output is valid when the measured value is less than the lower limit, and is invalid when the measured value is more than the lower limit plus hysteresis.

★Input start working mode (optional)

 Function description: In this working mode, short-connect the 3 and 4 terminals of the instrument within one second, can start the first and second group of relay closure and output effectively. When the measured value is more than the set value, the relay disconnect output is invalid until the next time, short connect the 3 and 4 terminals to output a valid bit for one cycle. This working mode is often used for single material loading stop, liquid filling and other batching occasions, which can make the supporting electronic control simpler and more convenient and efficient.

★Peak holding mode (optional)

 Function description: This mode of operation, by pressing the K3 key, can be switched to AXXXX (the peak measurement interface), which can maintain the last peak value, when the next measurement value is more than the ED-03 parameter (this is the peak threshold parameter) The last peak can be automatically overwritten to maintain this peak.

2.2 Terminal connection and hole size

(When the meter is in transmission output, the No.1 is negative and the No.2 is positive)

Menu structure

2.3.1 Parameter modification

In the standby state, long press [k1] + “enter the password to enter”, and the password is set to 100. Enter advanced parameters (parameters after 13) set password 105, higher parameter set password 110.

The specific operation steps are as follows: long press [k1], 00000 will appear. First, press [k4] to move the flashing digit, move to the flashing digit to be modified, press [k3] to modify the flashing digit. After the password is modified correctly, press [k1] will enter the group parameters, then press [k1] to switch the group parameters, when switch to the parameter to be modified, press [k4] to enter the parameter. After completing modification, press [k1] to confirm, Press [k2] to return to the measurement.

2.3.2 Weight calibration

In standby mode, long press [k2]. See the third page for details (3. calibration method)

2.3.3 Reset key

In standby mode, long press [k4] and complete the reset when the measured value is less than the reset range.

2.3.4 Restore factory settings

According to 2.3.1, enter the parameter modification (but need to use special password when entering the password) to switch to the 42nd parameter, input the number between 11-19, input 19 is the most common working mode, then press [k1] to switch to the next parameter, then press [k2] to exit, that is restore the meter parameters to the initial state of Mode 1-9.

2.3.5 Data backup

The operation method is the same as 2.3.4, enter the number 20 (see attached table).

Display information

The upper row of the meter displays the real-time value, and the lower row shows the information as shown in the following table:

Calibration method

Hardware calibration method

If there is no large weight or standard weight to replace the heavy object, can use calibration coefficient to calibrate. The radix point should be modified to the appropriate position according to the range of the sensor. The maximum display range of the instrument should not exceed 29999. (How to modify the radix point, please see 2.3.1)

Press a known weight (set to X). After stabilization, record the meter display value (set to Y), find the No. 36 parameter (how to enter the details to see 2.3.1), press K4 to view the value of the parameter (set to Z). By pressing the K4 key to move and the K3 key to modify the number, modify the number of parameter No. 36 to (Z*X/Y): the actual weight divided by the display weight and multiplied by the number got in 36th parameter. Press K1 to confirm, K2 to return, if it is not accurate, repeat the above steps.

Weight calibration method

Before calibrating the sensor, modify the radix point to the appropriate position according to the range of the sensor. Make sure that the maximum display range of the meter cannot exceed 29999. (How to modify the radix point, please see 2.3.1)

In standby state, long press [k2], “三 0xxxx” appears, press [k4] to zero clearing. If appear “三00000”, zero calibration is completed. Press [k2] to display “C0000”, plus weight or known standard weight, turns into “C0xxxx” (the weight must be greater than one tenth of the sensor range, otherwise the calibration is unsuccessful), first press [k4], then by pressing [[k3] to increase the value + [k4] to move the flashing digit, modify the weight of the weight. After stabilization, press [k2] to confirm, the calibration is completed, and the displayed value should be consistent with the weight of the weight. If it is not accurate, set again in the same order. After calibration is correct, press [k1] to return to the force measurement interface.

Digital calibration method

If there is no known weight, you can do it by digital calibration. First enter the sensor’s range in parameter No. 31, input the sensor sensitivity in parameter No. 32, then enter 40 in parameter No. 42, then press K2 to exit, then complete digital calibration automatically. When using multiple sensors, the input range is the sum of all sensor ranges

This calibration method must accurately know the sensitivity of the sensor. Generally, the sensitivity of the sensor is divisors, so this method cannot be accurately calibrated. Please use it with caution.
