The EMC1074 supports reading two external diodes on the same set of pins (DP2 / DN3 and DN2 /
DP3). These diodes are connected as shown in
diodes, both diodes will be reverse biased by a V
reverse bias, only discrete 2N3904 diode-connected transistors are recommended to be placed on
these pins.
The EMC1073 can be configured to measure a discrete 2N3904 diode-connected transistor or an AMD
processor diode. The diodes can be connected as shown in
Configurations".
The EMC1074 can be configured to measure a CPU substrate transistor, a discrete 2N3904 diode-
connected transistor, or an AMD processor diode on the External Diode 1 channel. The External Diode
2 and External Diode 3 channels are configured to measure a pair of discrete anti-parallel diodes
(shared on pins DP2 / DN3 and DN2 / DP3). The supported configurations for the external diode
channels are shown in

In default mode, all temperatures < 0°C will be reported as 0°C.
In the extended range, all temperatures < -64°C will be reported as -64°C.
For the default range, all temperatures > +127.875°C will be reported as +127.875°C.
For the extended range, all temperatures > +191.875°C will be reported as +191.875°C.
