CHAPTER 4 POWER REQUIREMENTS The Model 700 is supplied in either one of two power options: Standard or Heavy- Duty. A. STANDARD OPTION. Power is supplied by 4 “D” size NiMh rechargeable batteries. Also standard “alkaline” “D” batteries can be used to operate the instrument.
CHAPTER 5 SAMPLE FLOW & SAMPLE CONDITIONING SYSTEM The ENERAC Model 700 can accommodate any one of the three available sample conditioning systems. These range from the simplest water trap and latex hose conditioning system, to the recommended Teflon/Viton hose and thermoelectric condenser system, to the most sophisticated Teflon/Viton and permeation Drier system.
Page 28
The fiber filter should be replaced when it becomes noticeably discolored. 2. THERMOELECTRIC CONDENSER AND TEFLON/VITON HOSE This is the standard option for the Model 700. It is recommended for most applications where condensation removal without significant loss of the NO fraction of the sample is required.
Page 29
The following table shows the approximate relation between duty cycle and temperature differential: DUTY CYCLE SAMPLE TEMP AMBIENT TEMP (°F)* 100% *At 75°F ambient. The duty cycle of the thermoelectric cooler is set at the factory to 70% and can be adjusted as follows 1.
Page 30
20% (the maximum capacity of the permeation drier). 3. PERMEATION DRIER CONDITIONING SYSTEM This is a unique and proprietary conditioning system developed by ENERAC and used in its previous Model 3000E series of emissions analyzers. It has the major advantage of removing all excess water vapor from the sample without allowing any condensation to take place.
Page 31
A. The inconel probe The inconel probe is a five-piece assembly of metal tubing. It consists of the following parts. The gas extraction probe. This is a 3/8" diameter piece of inconel tubing that is threaded to the probe housing. The instrument thermocouple is located inside this tube.
Page 32
A’. The stack-velocity (S-V) probe. (OPTIONAL) If the ENERAC is equipped with (S-V) type of probe option, the section of the ENERAC’s probe that is inserted in the stack consists of three sections. You must never operate the instrument without the sintered filter.

Two pieces of flexible high temperature Viton hose connect the Pitot tube to the low-pressure sensor located inside the probe case.
Page 34
Nitrogen dioxide and to a lesser extent sulfur dioxide react readily in water and any condensation present in the hose assembly would result in erroneous readings. The probe housing consists of the following components a. The secondary fiber filter. This is a small cylindrical 0.5 micron glass fiber filter for the removal of the finer particles from the gas stream.
Page 35
If the pressure in the stack exceeds +4" W.C., the "NO FILTER OR FLOW" LED will turn on. You should ignore this LED and proceed with your measurements! This is common in engine measurements, when the ENERAC probe is located in front of a catalytic converter.
Page 36
RED and OFF. Once the probe is inserted in the stack its status will depend on the temperature of the drier manifold. If this temperature becomes high, the LED will turn GREEN, indicating that the ENERAC heat pump has switched to cooling the manifold.
CHAPTER 6 SENSORS The great versatility of the Model 700 Emissions system is partly due to the large number of sensors available within a single analyzer. These sensors are primarily gas sensors and can be grouped into three categories based on their principle of operation: 1.
Page 38
EPA CTM-022 protocol requirements. The SEM NO sensor of the ENERAC Model 700 is superior to the typical electrochemical type sensor in accuracy, interference rejection, and its design for continuous operation. Its inboard disposable filter has an estimated life in excess of 100,000 PPM-hours against sulfur dioxide.
Page 39
The ENERAC 700 uses a second pump to draw dilution air that enables the analyzer to extend the range of the sensors by a factor of at least 4, and also...
Page 40
To obtain an accurate high range reading the ENERAC 700 uses an additional calibrated oxygen sensor. By combining the reading of the sample oxygen sensor and the dilution oxygen sensor an accurate calculation of the gas concentration for the high range is obtained. The figure below shows an outline of the sensor configuration.
Page 41
It is possible in principle to clean the gas cell, but it is a costly and time-consuming operation. NOTE: If the ENERAC is equipped with the NDIR option, the analyzer will enter an autozero countdown each time it is turned on. Consequently, you must...
Page 42
The NDIR bench is designed for operation primarily with measurements of engine exhausts, according to the California BAR 97 regulations. The hydrocarbons sensor is tuned to the absorption band of propane. However, it will respond to other hydrocarbons with different sensitivity. 3.

The instrument must be started in a true "zero" environment. Otherwise it will assume as "zero" non-zero conditions and give erroneous readings. Never autozero the ENERAC, if the probe tip is still hot following a recent measurement.
Page 52
ZERO ALL SENSORS At the end of the autozero period the ENERAC reads the output of all sensors and sets them all to zero, with the exception of the oxygen that it sets to 20.9%. (The ambient temperature is read directly). Consequently, it is very important that at the moment of "zeroing"...
Page 53
You can carry out all span calibrations in sequence or just one, if you wish. You can use your own span gas, or if you need to calibrate the ENERAC in the field, you can use the convenient gas calibration kit supplied by ENERAC.
Page 54
Set up your calibration apparatus as shown in the figure below. You must not feed gas to the ENERAC under pressure and you must not starve the ENERAC's pump for gas. When feeding the gas to the ENERAC you must maintain a reasonably constant pressure.
Page 55
1. Connect the calibration apparatus and cylinder to the instrument. 2. Press the DATA key and observe the appropriate reading as you open the calibration cylinder valve. (If you are using the bypass flow meter, adjust the cylinder valve for a bypass flow rate of approximately 500 cc/min. Observe the readings of the other gas parameters for evidence of cross sensitivity and also the oxygen reading for confirmation that there is no instrument leak!
Page 56
Very slowly start closing the intake valve of the apparatus and observe the manometer reading climbing. Set the valve opening as soon as the manometer is reading the same pressure as that selected on the display. Press the ENTER again. The draft sensor will be calibrated to the value shown on the display.
If a command doesn’t contain a question mark it will cause the ENERAC to store the data sent with the command, or take some other action, such as erasing a specific data buffer. This is the way to reprogram the instrument from a remote location.

CHAPTER 12 MAINTENANCE The ENERAC micro-emissions analyzers are sophisticated analytical instruments designed to perform accurate emissions measurements. However, because they are hand-held instruments that find uses in many environments, care must be taken to prevent physical and environmental abuse. This will help maintain trouble-free operation.
Page 65
It will gradually drop with use until at 4.0 volts a “BATTERY LOW” warning will appear. You can estimate the remaining time by observing the battery voltage. For NiCd or NiMH rechargeable batteries the battery voltage will stay at approximately 4.8 volts for a long time and then drop rapidly. To replace the batteries, remove all the screws that secure the analyzer’s back plate.
