4. REGISTER TABLES

NOTE. Highest number of registers (or bytes) which can be read with a single command:
• in RTU mode: 127 registers
• in ASCII mode: 63 registers
• in TCP mode: 256 bytes
NOTE. Highest number of registers which can be programmed with a single command:
• in RTU mode: 29 registers
• in ASCII mode: 13 registers
• in TCP mode: 1 register
NOTE. The register values are in hex format ($).
NOTE. The following registers describe all parameters for any instrument configuration. Refer
to the instrument model before sending reading/writing commands: some register parameters
may not be available.

MEANING
Measuring parameter to be read
Description of the register to be read / written
Function code in hex format. It identifies the command type (reading / writing)
If this column is checked, the read register value can have positive or negative sign.
The value conversion changes according to the instrument model.
SIGN BIT
Convert a signed register value as shown
in the following instructions:
The Most Significant Bit (MSB) indica-
tes the sign as follows: 0=positive (+),
1=negative (-).
N :
