4-Wire Measurement
For the best performance in accurate voltage measurement, the TECPak
supports remote voltage measurement for the TEC using a 4-wire Kelvin
connection. To use remote TEC voltage sense, wire pins 2 (+) and 9 (–) to the
corresponding terminals as close to the TEC module as is reasonable.
To enable the remote TEC voltage sense function, send a TEC:VENSE 1. The
reported TEC voltage will now be measured through pins 2 and 9 instead of
TEC+ and TEC- at the instrument. When VSENSE is enabled, the TEC:CABLER
setting is ignored.
CAUTION
Do not confuse remote TEC voltage sense with the
remote sensor input (pins 10 & 11 on the 17W2
connector), as they are two very different functions, and
crossing their functionality could damage the instrument
or the mount.
