leaving the factory. Press to start, press
or to display 0mA, 4mA, 8mA, 12mA,
16mA, 20mA, and at the same time, check with an
ammeter to measure the current loop output current
and calculate the differences to see if it is under the
permitted tolerance. If not, refer to the "Analog
Output Calibration" to
calibrate.
CL Checkup [58
Press ENT When Ready
CL Current Output
Display CL current output. The display of 10.0000mA
indicates that CL current output value is 10.0000mA.
If the difference between displaying value and CL
output value is too large, the current loop then needs
to be re-calibrated accordingly.
CL Current Output [59
15.661mA

Serial Port Settings
This window is used for serial port setting. Serial port
is used to communicate with other instruments. The
serial port parameters setting of the instrument that
applies the serial port connection must be consistence.
The first selected data indicates baud rate, 9600,
19200, 38400, 56000, 57600, 115200 are available.
The second option indicates parity bit, None (No
verification).
Data length fixed to 8;
Stop bit length for a fixed length.
The factory default serial port parameter is "9600,
None".
