Page 6: Setting-Up
Chapter 2 Setting-Up Supplying Power The flowmeter can be powered in one of two ways: through the power jack using the supplied AC adapter or through the mini-DIN connector. The DC power input connector is shown below along with the power requirements. Power Supply: 7.5 VDC ±... -
Page 7: Connecting Filter And Flow Tubes
Connecting Filter and Flow Tubes The Models 4040/4043/4045 have an exposed thermal flow sensor, which must be protected from foreign matter and particles in the gas flow. TSI has supplied a filter, which should be connected to the inlet of the flowmeter; however, any filter will work as long as it has a minimum efficiency of 99.9%. -
Page 8: Configuration Software
Configuration Software TSI has several software utilities to help you communicate with your flowmeter to change parameters and to obtain flow data. You can download the latest versions of these at no charge from our web site: 1. If you only want to change one or more of the operating parameters shown in Table 3 (above), the easiest way is to use the software utility called “TSI setup.”... -

LCD display, RS232 serial port or the linearized analog output. The analog output is a 0 to 10 volt DC linear signal representing 0 to 300 Std L/min (Model 4043: 200 Std. L/min) (analog output scaling is user selectable). Refer to the RS232 Serial Command Set manual for instructions on how to obtain flow data through the serial port. -

LCD display. Refer to the Models 4040/4043/4045 RS232 Serial Command Set manual for instructions on using the volume function. TSI instruments defines standard conditions as 21.1°C (70° F) and 101.3 kPa (14.7 psia, 1 bar). Chapter 3 GlobalTestSupply www. -
Page 11: Maintenance
Re-certification To maintain a high degree of confidence in the measurements made by the Models 4040/4043/4045, TSI recommends that you return the instrument to TSI every 12 months for re-certification. For a nominal fee, we will recalibrate the unit and return it to you with a certificate of calibration and US National Institute of Standards Technology (NIST) traceability. -

Page 17: Standard Flow Rate Vs. Volumetric Flow Rate
Since thermal flow sensors are sensitive to changes in air density and air velocity, all thermal flowmeters indicate flow rates with reference to a set of standard conditions. For TSI instruments, standard conditions are defined as 21.1° C (70° F) and 101.3 kPa (14.7 psia). Other manufacturers may use different values.
