SSD Series – Riedon™ Digital Current Sensor with RS485/MODBUS Interface by Bourns

SSD Interface Manual (continued)

GK / SK GET / SET VBUS FACTOR

Used to adjust the Bus Voltage reading from the factory calibration. This is typically not necessary and the correct equipment is

essential to properly set it. See reset command to set the value back to factory default. Voltage is calibrated at 25 °C. Power and

Energy values are scaled appropriately.

Value is an unsigned Int16. Value is divided by 10000 in firmware to create the factor.

Example: To set VBUS FACTOR to 10023

GJ / SJ GET / SET VBUS ZERO OFFSET

Used to override the bus voltage zero offset. Value can be reset back to factory defaults.

Value is a signed Int16 in mV.

Example: To set VBUS OFFSET to -6 mV

GO / SO GET / SET TEMPERATURE OFFSET

Used to adjust the Temperature reading from the factory calibration. This is typically not necessary. See reset command to set the

value back to factory default.

Value is an Signed Int16 in 0.1 °C

Example: To set TEMP OFFSET to -2.2 °C send -22
