4–2 TM-XR9B-01XN
You can calibrate the Ethernet/RS-232 Interface for:
• Voltage program
• Voltage readback
• Current program
• Current readback
• Overvoltage protection
The following equipment will be required to accurately calibrate your
unit:
• Digital Voltmeter, 5 1/2 digit, 0.1% accuracy or better, with test leads
• Current sensing shunt resistor, rated for 150% of maximum output
current, 0.25% accuracy or better
• Connection wires rated for the unit's maximum output current and
voltage
• A network ready, or RS-232 equipped computer to send the
calibration commands to the unit
Calibrate the unit according to the following procedures, referring to
“Command Reference” for more information about the calibration
commands used.
The calibration procedures in this section are designed to be performed at
an ambient temperature of 25°C ± 5°C.
