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.
