Voltse() Instruction; Mounting - Campbell EE181 Product Manual

NOTE:
Short Cut cannot edit programs after they are imported and edited in CRBasic Editor.
A Short Cut tutorial is available in
CRBasic Editor to create or add to a customized program, follow the procedure in
Short Cut code into CRBasic Editor
provided in the following sections. Complete program examples for select data loggers can be
found in Example programs
Measure the EE181 with the
section.

VoltSE()
7.2.1
When cable lengths are shorter than 6.1 meters or when power is switched, use the
measurement instruction to measure the temperature and relative humidity. The EE181 output
scale is 0 to 1000 millivolts for the temperature range of –40 to 60 °C and for the relative humidity
range of 0 to 100%.
VoltSE(Dest, Reps, Range, SEChan, MeasOff, SettlingTime, Integ/FNotch, Mult, Offset)
Variations:
Temperature reported as °C – set Mult to 0.1 and Offset to –40
l
Temperature reported as °F – set Mult to .18 and Offset to –40
l
Humidity reported as a percent – set Mult to 0.1 and Offset to 0
l
Humidity reported as a fraction – set Mult to 0.001 and Offset to 0

NOTE:
When the probe is connected to a CS110 Electric Field Meter, the probe is measured by the
CS110 internal CR1000 data logger module using
and temperature signals are measured on single-ended terminals 1 and 2, respectively.

Sensors should be located over an open level area at least 9 m (EPA) in diameter. The surface
should be covered by short grass or the natural earth surface where grass does not grow.
Sensors should be located at a distance of at least four times the height of any nearby
