Run Screen - Applied Instruments XR-3 Operation Manual

XR-3 TS2 Module Operation Manual
Allows voltage supplied by IDU / IRD to power the LNB extending the battery life of meter

However, the meter itself is always powered by its internal battery or by the external AC to DC
switching power supply while connected to AC power.
Note: In order to prevent damage to the meter's circuitry, do NOT input more than 30 volts to the
XR-3's TS2 module.

d) Voltage provided to LNB (13, 18, 21, or 29 volts)
4) Signal Level
a) Left bar graph (with peak hold center line)
b) Numeric value in dBm, dBmV, or dBµV
c) Scale: -75 to -15 dBm (-26 to +34 dBmV)or (+34 to +94 dBµV)
5) Signal Quality
