Page 5: Introduction
This document is organized with the most important information grouped together for easy reference by the user. All ES-405 owners and operators should read and understand the sections on installation, setup, and field calibrations. Other sections that provide in-depth information on subjects such as theory, diagnostics, accessories, and alternate settings provide valuable information which should be consulted as needed. -
Page 6: About The Es-405
ES-405 measurement modes can be found in Section 5. Laser Light Scatter System Sample air is drawn into the ES-405 detector chamber and subjected to an intense laser beam located at right angles to the flow. Particles pass through the laser beam and scatter light that is collected onto a photodiode detector. -

Page 8: 405 Setup And Startup
2 ES-405 SETUP and STARTUP The ES-405 is designed for rapid deployment and easy setup by a single person in less than 15 minutes in most applications. This section describes the basic assembly, setup, and start-up of the instrument. 2.1 Standard and Optional Accessories When unpacking a new ES-405, verify that the contents are undamaged. -
Page 9: Wall Or Pole Mounting
EX-905 tripod with supplied fittings. Install the MET sensor on the end of the cross-arm. The sensor should be as far from the ES-405 unit as possible without affecting the tripod balance. If a wind vane is employed, it must be able to rotate fully without hitting anything. - Page 10 10” ES-405 Total Height: ( 6” deep ) 70” 905 Tripod (optional) 48” AC to 12 VDC Power Supply Standard ES-405 Configuration 41” triangular Not to scale.

RS-232 communications. 2.5 Power-Up and Starting Operation As soon as power is applied to the ES-405, the unit will boot up and display ES-405 and company website for a few seconds. The ES-405 will then default to the OPERATE screen as shown below and begin sampling. -
Page 12: Default Setup
175 deg 2.6 Default Setup The ES-405 is factory configured to measure continuously with one-minute sample. The following table lists some of the factory default configurations which may need to be changed for your application. See Section 6 for details about the settings. -
Page 13: Site Selection And Remote Power Options
• If an ES-405 is to be collocated at a station along with BAM or FRM samplers, the inlets of each sampler must be no less than one meter apart from each other, and no more than four meters apart. -
Page 14: Fall Hazard And Security Cautions
3.2 Fall Hazard and Security Cautions If the ES-405 is to be installed more than three meters above ground level, then the tripod legs must be bolted down to prevent the unit from falling to the ground. An accidental fall may cause major optical system damage requiring that the unit be returned to the factory for repairs. -
Page 15: 405 User Interface And Menu System
4 ES-405 USER INTERFACE and MENU SYSTEM This section describes the ES-405 user interface system, and describes the functions of the main menu options, including how to view data and errors. 4.1 The User Interface - Keypad and Display Functions The ES-405 user interface consists of a 4x20 character organic light-emitting diode display (OLED) and a dynamic keypad. -
Page 16: Using The Main Sampling Screen
Not all the parameters monitored by the ES-405 can fit on the screen, press the down ▼ arrow to view the remaining parameters. The date and time will remain at the top of the display at all times. -
Page 17: Using The Main Es-405 Menu System And Clearing Memory
ALARMS ABOUT The main ES-405 menu system can be entered at almost any time by pressing the MENU key. Use the ▲▼ arrow keys to select the desired menu option, then press the MENU key to enter the selected sub-menu. The functions in the SETUP and CALIBRATE menus are described in Section 6 and 7. -
Page 18: 405 Measurement Method
Sample air is drawn into the ES-405 by an internal pump. Flow rate is controlled with a flow sensor to maintain constant 1LPM flow on the inlet nozzle. Additional air is added around the sample flow to contain the particles. -
Page 19: Sample Rh Control For Light Scatter Mass
24-hour data. Calculate the K-Factor for each particulate size fraction as the reference total concentration divided by the ES-405 total light scatter concentration over the same time period. For example, if the reference total concentration was 51 μg/m and the ES-405 total concentration was 38 μg/m... -
Page 20: Setup Menu Descriptions
SETUP menus will not need to be changed by the site operator. The settings will not be lost if the unit is unplugged or powered down. The SETUP menu can be accessed through the main ES-405 menu. Use the arrow keys to select SETUP option in the main menu, then press the MENU key to enter the menu. -

Page 22: Calibrate Menu - Field Calibrations
7 CALIBRATE MENU – FIELD CALIBRATIONS The ES-405 has a system of calibration menus which allow the operator to audit or calibrate the airflow control system parameters for optimal performance. These parameters are often audited monthly and calibrated quarterly during continuous operation. The exact frequency may vary... -
Page 23: Calibrate Fp Screen
DEFAULT CALIBRATE The FP parameter is the current reading from the ES-405 pressure sensor. The STANDARD parameter is where you can enter the correct value from your traceable pressure standard, using the arrow keys. You will need to convert units if your standard outputs pressure in other units. The FP value should change to match the STANDARD value when you press the CALIBRATE soft key. -
Page 24: Maintenance And Troubleshooting
This section provides information about routine maintenance of the ES-405, and for performing more detailed diagnostic tests if a problem is encountered. The ES-405 generates error messages on the display or in the data log if a failure or other problem is detected. Many times, there is a simple solution. -
Page 25: Suggested Periodic Maintenance Intervals
AQ Flow Calibration Connect a flow meter to the inlet nozzle of the ES-405 Particle Profiler and allow the flow to stabilize. If it is not 1.00 LPM ± 0.02LPM, then it needs to be calibrated. Refer to Section 7.1.1. -
Page 26: Factory Service Interval
Factory Service Interval The ES-405 needs to be periodically returned to the factory for service and recalibration. The recommended period is 24 months during continuous use. However, some users establish their own interval depending on the harshness of the sampling conditions, particulate levels, and data scrutiny. -
