Reading Internal Temperature Measurements
Internal temperatures are measured by the channels of a fan controller. The Series 2268
850-Watt power supply has one fan controller, Fan0, with two channels, 0 and 1, that each
control a fan and measure temperature.
The SCPI command (s) for these readings are:
DIAGnostic:MEMory:FAN<n>:READ #h0<n>
Example: to read the temperatures in the Series 2268 850-Watt power supply,
DIAG:MEM:FAN0:READ #h00
//this reads the 1st channel
DIAG:MEM:FAN0:READ #h01
//this reads the 2nd channel
