Use the equation that follows to calculate the expected voltage. Make sure that the measured
and calculated voltages agree.
Voltage = < (0.002 × RL)
Where: RL = value of the load resistor in ohms
Example: for a 100-ohm resistor, the voltage should be less than 0.20 V.

On the Basic Setup tab, change the settings back to the previous values.

RS485 serial output with Modbus RTU protocol
Instruments with the RS485 Modbus communication option use industry-standard Modbus RTU
protocol. In this communication mode, a series of registers hold data about measurement results
and operation parameters.
When a ModbusTCP connection is made, the user can use all the configuration options in the
Modbus register map. Refer to the company website for the Modbus register map. Write drivers to
communicate with the instrument through these registers with the Modbus RTU protocol.
The RS485 serial network circuit supplies communications for a maximum of 32 instruments and a
control computer. Only one instrument can transmit data at a time. Each instrument must have a
unique instrument address.
