Quick-Select modules when installed in the base unit are referred
to as Channel 1 and Channel 2. Channel 1 is always the module
on the left side of the calibrator when it is held upright with mod-
ules at the top of the calibrator and the LCD display facing the
operator. Channel 2 is on the right side when the base unit is
held in the same position.
AM2-1 pressure modules are low pressure measurement devices
based on micro machined silicon variable capacitance sensors.
They are intended for use with clean dry, nonconductive, non-
corrosive gases. They are available in ranges from 0.25 to 200
inches of water column and can be configured to provide differen-
tial, gauge or compound readings.
AM2-2 are high pressure measurement devices. They are sin-
gle-port modules based on sensors capable of measuring gauge,
absolute, compound or vacuum with ranges spanning from
vacuum to 5 psi to 10,000 psi. All wetted parts are 316 stainless
steel (except for 10k psi module which has 17-4ph stainless
steel) and are intended for use with any pressure medium com-
patible with stainless steel.
AM2-RT1 and RT2 modules are RTD temperature measurement
modules compatible with Pt100, Pt1000, Ni120, Cu10, and up to
six user programmable resistance curves. Measurements can be
displayed in degrees Fahrenheit, Celsius, Kelvin, Rankin or ohms.
The setup menu allows the operator to choose configurations
for 2, 3 or 4 wire RTD probes. In addition, the setup menu also
allows selection of 1, 0.1, 0.01 or 0.001 decimals of resolution.
Accuracy specifications are detailed in the data sheet.
