Chapter 4: Using the SM-2001U & SM-2003U
Overview
The SM-2001U and SM-2003U calibration stations are capable of
performing bump tests and calibrations on instruments and charging
rechargeable battery packs in instruments. This chapter describes
procedures for using the calibration stations to bump test, calibrate, and
recharge GX-2001 and GX-2003 instruments. It also describes the
information that is saved in a calibration station’s memory and how to
save that information to a USB flash drive.
Bump Testing Instruments
When a bump test is performed, the calibration station performs an air
adjust operation on an instrument and then applies calibration gas to the
instrument. The calibration station analyzes the response results based
on criteria defined by the MODE switch position and determines if the
instrument passed the bump test. The criteria set by the MODE switch is
defined in Table 4 on page 20.
To perform a bump test on an instrument:
1. Verify that the appropriate calibration gas cylinder is connected to
the CAL. GAS fitting on the back of the calibration station.
2. Verify that the MODE switch is in the position that defines the
desired bump test pass criteria. See Table 4 on page 20.
3. If the calibration station is off, turn it on using the power switch on
the back of the station. The CHARGE status LED will begin to blink
green.
4. Put the instrument to be bump tested into the calibration station. A
GX-2001 is placed into an SM-2001U and a GX-2003 is placed into
an SM-2003U.
• For a GX-2001, attach the flow adapter cup to the sensor side of
the instrument before inserting it into the SM-2001U.
• For the GX-2003, place the instrument into the SM-2003U,
connect the plastic fitting on the end of the coiled black tube to
