PROFIBUS. The corresponding communication mode should be set when the instrument is equipped with
different communication modes.
7.5.2 Instrument Communication Address
It means communication address of this meter when data communication, optional range:
• address 01 - 250, address 0 is reserved
7.5.3 Instrument Communication Speed
Instrument communication baud rate selection range: 300, 600, 1200, 2400, 4800, 9600, 19200, 38400.
7.5.4 Instrument Calibration Mode
The standard configuration of the converter is standard MODBUS communication. One stop bit 8-bit no
parity mode, users can choose one stop bit 8-bit odd parity, one stop bit 8-bit even parity mode, and two
stop bits 8-bit no parity mode, two stop bits 8-bit odd parity, and two stop bits 8-bit odd parity.

Parameter Modification Tag
7.6.1
User Password 1 - 4
Using the level 5 password allows the user to modify the passwords for all levels. Please contact your local

7.6.3 Positive Total High & Low
The total high and low setting can change the value of the forward cumulative total and the reverse
cumulative total, which is mainly used for instrument maintenance and instrument replacement.
User uses a 5-level password to enter, and can modify the positive cumulative amount (Σ+). Generally, the
cumulative amount cannot exceed the maximum value (999999999) counted by the counter.
7.6.4 Reverse Total High & Low
User uses a 5-level password to enter, and can modify the reverse cumulative amount (Σ-). Generally, the
cumulative amount cannot exceed the maximum value (999999999) counted by the counter.
