★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)
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.
