650 Quick Start Guide
1) Plug in the analyzer and turn the power on.
2) Connect the appropriate gas lines and vents to the analyzer.
3) Allow the analyzer to stabilize for at least one (1) hour.
4) During the analyzer’s stabilization period, setup the analyzer to the desired
configuration.
a) Set the analyzer’s output as desired.
i) From the Main Menu press F5 (Setup) then F7 (System Settings.)
ii) Press F3 (output assignments) to setup the output channels.
(1) Set to real time
(2) Set channel 2 to NO
(3) Set channel 3 to NO2
(4) Set channel 4 to O2
(5) Press back to return to the system settings menu.
iii) Press F4 (output range) to setup the output ranges
(1) Set the Min and Max to zero (0). This will cause the outputs to
default to the analyzer ranges.
(2) Set the outputs for milliamps (mA) or voltage (V) as desired.
(a) The mA setting will give 4-20 mA or 2-10V (if 500 ohm
resisters are installed).
(b) The V setting will give 0-20mA or 0-10V (if 500 ohm resistors
are installed).
5) Connect all appropriate analog outputs.
a) Pin 1 is the output common (ground).
b) Pins 2, 3, 4, and 5 are output channels 1, 2, 3, and 4 as setup in step 4.a.ii.
c) If the output is set for voltages but there is no voltage output, you will need to
install a 500 ohm resistor between pin 1 and the channel you are trying to
measure. You will have to measure the voltage drop across this resistor.
6) Press F1 from the analyzer’s main Menu to get to the measurement screen.
a) The individual NO, NOx, and NO2 channels only work while measuring in dual
mode. (Real time and O2 output continuously)
b) Press F2 while in the measurement screen to get to dual measurement mode.
7) Supply sample gas to the analyzer.
8) The measurement screen should indicate the concentration of the sample gas. If
the concentration is incorrect, the analyzer will need to be Zeroed and Spanned
using your calibration gases. Please reference the appropriate section of the
manual for a description on how to zero and span the analyzer.

1. Introduction
1.1. Overview
Congratulations and thank you! You have just purchased one of the most reliable gas
analyzers in the world. Before using the analyzer, please familiarize yourself with its operation
by reading this manual. If you have any questions, please do not hesitate to call California
Analytical Instruments for assistance. We want you to be a member of our thousands of
satisfied customers.
1.2. Unpacking Instructions
Open the shipping container and carefully remove the analyzer from the packing materials.
Inspect the instrument for any sign of damage. Remove the Top Cover retaining screws.
Visually check for loose parts or connectors that are not properly seated. Verify all circuit
boards and circuit board connections are secure. If all internal components look normal, re-
install the cover.
1.3. Reporting Damage
Should there be any apparent damage to either the inside or outside of the instrument due to
shipping or handling, immediately notify the shipper. The shipping container or packing
materials should be retained for inspection by the shipper.
