markings.
3. Replace the cover. Replace the three screws.
IMPORTANT!
Alkaline batteries cannot be recharged. The instrument’s internal
circuit detects alkaline batteries and will not allow recharging. If you
place the instrument in its Travel Charger or Charger Stand, the
alkaline battery will not be recharged. The internal charging circuit is
designed to prevent damage to alkaline batteries and the charging
circuit when alkaline batteries are installed inside the instrument. If
you try to charge an alkaline batteries installed in the instrument, the
Charging Cradle or Travel Charger’s charging LED does not glow,
indicating that it will not charge the alkaline batteries.
Note: When replacing alkaline batteries, dispose of old ones properly.
15
UltraRAE 3000 User’s Guide
6 Charging A Lithium-Ion Battery
Always fully charge the battery before using the instrument. The
instrument’s Li-ion battery is charged by attaching the instrument to
the Travel Charger (or by placing the instrument in the optional
Charger Stand). Contacts on the bottom of the instrument meet the
Travel Charger’s (or Charger Stand’s) contacts, transferring power
without other connections.
Travel
Charger
Charger Stand
Note: Before connecting the charger to the instrument, visually
inspect the contacts to make sure they are clean. If they are not, wipe
them with a soft cloth. Do not use solvents or cleaners.
Follow this procedure to charge the instrument:
1. Plug the AC/DC adapter’s barrel connector into the
instrument’s Charger Stand or Travel Charger.
2. Plug the AC/DC adapter into the wall outlet.
3. Connect the AC/DC adapter to the Travel Charger (or

16
UltraRAE 3000 User’s Guide
4. Place the instrument into the Travel Charger or Charger Stand.
The LED in the Travel Charger (or Charger Stand) should
glow.
The instrument begins charging automatically. (If the optional
Charger Stand is used, the “Primary” LED blinks green to
indicate charging.) During charging, the diagonal lines in the
battery icon on the instrument’s display are animated and you see the
message “Charging...”
Note: If the Li-ion battery has been discharged below a certain
threshold, the “Charging...” message does not display immediately.
The charging LED blinks to indicate that it is charging, and after it
has been charging for a while, the “Charging...” message appears.
When the instrument’s battery is fully charged, the battery icon is no
longer animated and shows a full battery. The message “Fully
charged!” is shown. (If the Charger Stand or Travel Charger is used,
its LED glows continuously green.)
Note: If you see the “Battery Charging Error” icon (a battery
outline with an exclamation mark inside), check that the
instrument or rechargeable battery has been properly set into
the Travel Charger (or Charger Stand). If you still receive the
message, check the Troubleshooting section of this guide.
Note: If the instrument or battery has been charging for more than 10
hours and you see the “Battery Charging Error” icon and a message
that says, “Charging Too Long,” this indicates that the battery is not
reaching a full charge. Try changing the battery and make sure the
contacts on the instrument are meeting the Travel Charger’s (or
Charger Stand’s) contacts. If the message is still shown, consult your
distributor or RAE Systems Technical Services.
17
UltraRAE 3000 User’s Guide
6.1 Charging A Spare Rechargeable Battery
(Optional Charger Stand Only)
A rechargeable Li-ion battery can be charged when it is not inside the
monitor. The Charger Stand is designed to accommodate both types
of charging. Contacts on the bottom of the battery meet the contacts
on the Charger Stand, transferring power without other connections,
and a spring-loaded capture holds the battery in place during
charging.
1. Plug the AC/DC adapter into the Charger Stand.
2. Place the battery into the Charger Stand, with the gold-plated
contacts on top of the six matching charging pins.
3. Plug the AC/DC adapter into the wall outlet.
The battery begins charging automatically. During charging, the
Secondary LED in the Charger Stand blinks green. When charging is
complete, it glows steady green.
Release the battery from the Charger Stand by pulling it back toward
the rear of the Charger Stand and tilting it out of its slot.
Note: If you need to replace the Li-ion battery pack, replacements are
available from RAE Systems. The part number is 059-3051-000.
WARNING!
To reduce the risk of ignition of hazardous atmospheres, recharge
and replace batteries only in areas known to be non-hazardous.
6.2 Low Voltage Warning
When the battery’s charge falls below a preset voltage, the
instrument warns you by beeping once and flashing once every
minute, and the “empty battery” icon blinks on and off once
per second. You should turn off the instrument within 10
minutes and either recharge the battery by placing the
18
UltraRAE 3000 User’s Guide
instrument in its cradle, or replace the battery with a fresh one with a
full charge.
6.3 Clock Battery
An internal clock battery is mounted on one of the instrument’s
printed circuit boards. This long-life battery keeps settings in memory
from being lost whenever the Li-ion battery or alkaline batteries are
removed. This backup battery should last approximately five years,
and must be replaced by an authorized RAE Systems service
technician. It is not user-replaceable.
6.4 Data Protection While Power Is Off
When the instrument is turned off, all the current real-time data
including last measured values are erased. However, the datalog data
is preserved in non-volatile memory. Even if the battery is
disconnected, the datalog data will not be lost.
19
UltraRAE 3000 User’s Guide
7 User Interface
The instrument’s user interface consists of the display, LEDs, an
alarm transducer, and four keys. The keys are:

8 Operating The Instrument
The instrument is designed as a broadband VOC gas monitor and
datalogger for work in hazardous environments. It gives real-time
measurements and activates alarm signals whenever the exposure
exceeds preset limits. Prior to factory shipment, the instrument is
preset with default alarm limits and the sensor is pre-calibrated with
standard calibration gas. However, you should test the instrument and
verify the calibration before the first use. After the instrument is fully
charged and calibrated, it is ready for immediate operation.
8.1 Turning The Instrument On (Simple)
1. With the instrument turned off, press and hold [MODE].
2. When the display turns on, release the [MODE] key.
The RAE Systems logo should appear first. (If the logo does not
appear, there is likely a problem and you should contact your
distributor or RAE Systems Technical Support.) The instrument is
now operating and performs self tests. If any tests (including sensor
and memory tests) fail, refer to the Troubleshooting section of this
guide.
Once the startup procedure is complete, the instrument shows a
numerical reading screen with icons. This indicates that the
instrument is fully functional and ready to use.
23
UltraRAE 3000 User’s Guide
8.2 Turning The Instrument On
(Power On Zero)
If your UltraRAE 3000 has been configured to perform a zero (fresh
air) calibration upon startup, called Power On Zero, then the startup
routine is interrupted so that you can perform a fresh air calibration.
(See page 85 for details on turning this feature on or off.)
If you do not want to perform a zero calibration, press [MODE] to
bypass it. If you start a zero calibration and want to abort it, press
[N/-], and the calibration stops and the main display is shown.
8.3 Turning The Instrument Off
1. Press and hold the Mode key for 3 seconds. A 5-second
countdown to shutoff begins.
2. When you see “Unit off...” release your finger from the
[MODE] key. The instrument is now off.
Note: You must hold your finger on the key for the entire shutoff
process. If you remove your finger from the key during the
countdown, the shutoff operation is canceled and the instrument
continues normal operation.
8.4 Operating The Built-In Flashlight
The instrument has a built-in flashlight that helps you point the probe
in dark places. Press the flashlight key to turn it on. Press it again to
turn it off.
Note: Using the flashlight for extended periods shortens the battery’s
operating time before it needs recharging.
24
UltraRAE 3000 User’s Guide
8.5 Pump Status
IMPORTANT!
During operation, make sure the probe inlet and the gas outlet are free
of obstructions. Obstructions can cause premature wear on the pump,
false readings, or pump stalling. During normal operation, the pump
icon alternately shows inflow and outflow as shown here:
During duty cycling (PID lamp cleaning), the display shows these
icons in alternation:

UltraRAE 3000 User’s Guide
9 Operating Modes
The UltraRAE is actually two monitors in one:
• Compound-specific monitor
• VOC monitor
As a compound-specific monitor, it takes timed measurements and
uses a separation tube in conjunction with software that enables the
UltraRAE 3000 to give specific readings on one particular type of
compound, such as benzene or butadiene.
As a VOC monitor, the UltraRAE 3000 operates in different modes.
In some cases, you can change modes using a password and using the
instrument’s navigation. In other cases, you must use ProRAE Studio
software.
The following two sections cover operation in the two modes.
• Compound Specific, 31.
• VOC, page 38.
The diagram on the next page shows the basic flow of the UltraRAE
3000’s functions. The area with the gray field is the compoundspecific (tube) mode, while the rest shows VOC mode. Navigate
through the steps by using the [Y/+] and [N/-] keys as shown in the
diagram.
Note: If you use a password to access Programming Mode (see page
60), then the navigation changes slightly, entering part of Advanced
Hygiene Mode’s settings, as shown on page 29.

10 Compound-Specific Operation
10.1 Compound-Specific Measurement
The UltraRAE 3000 can perform compound-specific measurement in
addition to general VOC measurement. This requires using a RAESep separation tube (butadiene or benzene) and having the UltraRAE
3000 in Tube Mode, operating with a 9.8eV lamp.
10.2 Measurement Phases
To perform a compound-specific measurement, follow this order:
1. UltraRAE 3000 is ready for sampling
2. Prepare the separation tube
3. Insert the separation tube
4. Start measurement
5. UltraRAE 3000 displays and logs measurement
6. Remove the separation tube
10.3 Performing A Measurement
Before performing a compound-specific measurement for Benzene or
Butadiene using a RAE-Sep separation tube, make sure the UltraRAE
3000 is in Tube Mode and that the appropriate tube type is selected.
The UltraRAE 3000 only acts as a compound-specific measurement
device when it is equipped with a 9.8eV lamp. The UltraRAE 3000 is
designed to auto-sense the lamp type. It can also be manually set to
default to a 9.8eV lamp type.
Make sure the UltraRAE 3000 is set to operate with your selected tube:
1. Enter Programming Mode.
2. Select Measurement.
3. Select Tube Selection.
4. Make a choice of Benzene or Butadiene.
5. Save your choice.

Before you start sampling, you must insert a RAE-Sep separation tube
into the inlet/holder. Follow the Separation Tube Preparation and Placing
A Tube Into The UltraRAE 3000 instructions before pressing any
buttons on the UltraRAE 3000. Once the tube is in place, then proceed to
measuring.
IMPORTANT!
Once a tube’s ends are broken off, the material inside is exposed.
Therefore, use the tube for sampling as soon as possible.
10.4 Separation Tube Preparation
CAUTION!
Wear hand and eye protection when breaking tube tips. Use caution
in handling tubes with broken ends. Keep away from children. RAESep tubes should be disposed of according to local regulations. See
footnotes of data sheets for disposal information.

12.3 Testing The Alarm
You can test the alarm whenever the main (Reading) display is
shown. Press [Y/+], and the audible and visible alarms are tested.
13 Integrated Sampling Pump
The instrument includes an integrated sampling pump. This
diaphragm-type pump that provides a 450 to 550 cc per minute flow
rate. Connecting a Teflon or metal tubing with 1/8" inside diameter to
the gas inlet port of the instrument, this pump can pull in air samples
from 200' (61 m) away horizontally, or 90' (27.5 m) vertically, at
about 3' (0.9 m) per second flow speed.
Note: In Search Mode, the pump turns on when a sample
measurement is started, and turns off when the sample is manually
stopped.
If liquid or other objects are pulled into the inlet port filter, the
instrument detects the obstruction and immediately shuts down the
pump. The alarm is activated and a flashing pump icon is displayed.
You should acknowledge the pump shutoff condition by clearing the
obstruction and pressing the [Y/+] key while in the main reading
display to restart the pump.

UltraRAE 3000 User’s Guide
14 Backlight
The LCD display is equipped with an LED backlight to assist in
reading the display under poor lighting conditions.
15 Datalogging
During datalogging, the instrument displays a disk icon to indicate
that datalogging is enabled. The instrument stores the measured gas
concentration at the end of every sample period (when data logging is
enabled). In addition, the following information is stored: user ID,
site ID, serial number, last calibration date, and alarm limits. All data
are retained (even after the unit is turned off) in non-volatile memory
so that it can be down- loaded at a later time to a PC.
15.1 Datalogging Event
When Datalogging is enabled, measurement readings are being saved.
These data are stored in “groups” or “events.” A new event is created
and stored each time the instrument is turned on and is set to
automatic datalogging, or a configuration parameter is changed, or
datalogging is interrupted. The maximum time for one event is 24
hours or 28,800 points. If an event exceeds 24 hours, a new event is
automatically created. Information, such as start time, user ID, site
ID, gas name, serial number, last calibration date, and alarm limits are
recorded.
15.2 Datalogging Sample
After an event is recorded, the unit records a shorter form of the data.
When transferred to a PC running ProRAE Studio, this data is
arranged with a sample number, time, date, gas concentration, and
other related information.
44
UltraRAE 3000 User’s Guide
15.3 Auto/Manual/Snapshot Datalogging
The instrument has three datalog types:
Auto Default mode. Collects datalog information when the
instrument is sampling.
Manual Datalogging occurs only when the instrument’s
datalogging is manually started (see page 63 for
details).
Snapshot Datalogs only during snapshot (single-event capture,
initiated by pressing [MODE]) sampling. See page 65
for details.
Note: You can only choose one datalog type to be active at a time.

17 Standard Kit & Accessories
17.1 AC Adapter (Battery Charger)
WARNING
To reduce the risk of ignition of hazardous atmospheres, recharge
battery only in area known to be non-hazardous. Remove and
replace battery only in area known to be non-hazardous.
Ne charger les batteries que dans emplacements designés nondangereuses.
A battery charging circuit is built into the instrument cradle. It only needs a
regular AC to 12 VDC adapter (wall-mount transformer, part number 5000114-000) to charge the instrument.
To charge the battery inside the instrument:
1. Power off the instrument.
2. Connect the AC adapter to the DC jack on the instrument’s cradle.
If the instrument is off, it automatically turns on.
3. While charging, the display message shows “Charging.” The
Primary LED on the cradle flashes green when charging.
4. When the battery is fully charged, the LED changes to glowing
green continuously, and the message “Fully charged” appears on
the display. If there is a charging error, the LED glows red
continuously.
A completely discharged instrument can be charged to full capacity
within 8 hours. Batteries drain slowly even if an instrument is off.
Therefore, if the instrument has been in storage or has not been
charged for several days or longer, check the charge before using it.
The factory-supplied battery is designed to last for 16 hours of normal
operation (no alarm), for a new battery under the optimum
circumstances. As the battery becomes older or is subject to adverse
conditions (such as cold ambient temperature), its capacity will be
significantly reduced.

UltraRAE 3000 User’s Guide
17.2 External Filter
The external filter is made of PTFE (Teflon®) membrane with a 0.45
micron pore size to prevent dust or other particles from being sucked
into the sensor manifold, which would cause extensive damage to the
instrument. It prolongs the operating life of the sensor. To install the
external filter, simply connect it to the instrument’s inlet probe.
47
UltraRAE 3000 User’s Guide
18 Optional Accessories
18.1 Calibration Adapter
The calibration adapter for the instrument is a simple 6-inch Tygon
tubing with a metal adapter on one end. During calibration, simply
insert the metal adapter into the regular gas inlet probe of the
instrument and the tubing to the gas regulator on the gas bottle.
18.2 Calibration Regulator
The Calibration Regulator is used in the calibration process. It
regulates the gas flow rate from the Span gas cylinder into the gas
inlet of the instrument during calibration process. The maximum flow
rate allowed by the flow controller is about 0.5L/min (500 cc per
min.). Alternatively, a demand-flow regulator or a Tedlar gas bag
may be used to match the pump flow precisely.
18.3 Organic Vapor Zeroing Kit
The Organic Vapor Zeroing Kit is used for filtering organic air
contaminants that may affect the zero calibration reading. To use the
Organic Vapor Zeroing Kit, simply connect the filter to the inlet port
of the instrument.

19.2 Zero (Fresh Air) Calibration
This procedure determines the zero point of the sensor calibration
curve. To perform a fresh air calibration, use the calibration adapter to
connect the instrument to a “fresh” air source such as from a cylinder
or Tedlar bag (optional accessory). The “fresh” air is clean, dry air
without organic impurities and an oxygen value of 20.9%. If such an
air cylinder is not available, any clean ambient air without detectable
contaminants or a charcoal filter can be used.
At the Zero Calibration menu, you can proceed to perform a Zero
calibration or bypass Zero calibration and perform a Span calibration.
You may also go back to the initial Calibration menu if you want to
exit calibration.
• Press [Y/+] to start calibration.
• Press [MODE] to quit and return to the main calibration
display.
If you have pressed [Y/+] to enter Zero calibration, then you will see
this message:
1. Turn on your Zero calibration gas.
2. Press [Y/+] to start calibration.
Note: At this point, you may press [MODE] if you decide
that you do not want to initiate calibration. This will take you
directly to the Calibration menu, highlighted for Span
calibration.
51
UltraRAE 3000 User’s Guide
3. Zero calibration starts a 30-second countdown and displays
this message:
Zeroing...
During the zeroing process, the instrument performs the Zero
calibration automatically and does not require any action on your part.
Note: To abort the zeroing process at any time and proceed to Span
calibration, press [N/-] at any time while zeroing is being performed.
You will see a confirmation message that says “Zero aborted!” and
then the Span calibration menu appears.
When Zero calibration is complete, you see this message:
Zeroing is done!
Reading = 0.0 ppm
The instrument will then show the Calibration menu on its display,
with Span Calib highlighted.
19.3 Span Calibration
This procedure determines the second point of the sensor calibration
curve for the sensor. A cylinder of standard reference gas (span gas)
fitted with a 500 cc/min. flow-limiting regulator or a flow-matching
regulator is the simplest way to perform this procedure. Choose the
500 cc/min. regulator only if the flow rate matches or slightly exceeds
the flow rate of the instrument pump. Alternatively, the span gas can
first be filled into a Tedlar bag or delivered through a demand-flow
regulator. Connect the calibration adapter to the inlet port of the
instrument, and connect the tubing to the regulator or Tedlar bag.
Another alternative is to use a regulator with >500 cc/min flow but
allow the excess flow to escape through a T or an open tube. In the
latter method, the span gas flows out through an open tube slightly
wider than the probe, and the probe is inserted into the calibration
tube.
52
UltraRAE 3000 User’s Guide
At the Span Calibration menu, you perform a Span calibration. You
may also go back to the Zero calibration menu or to the initial
Calibration menu if you want to exit calibration.
• Press [Y/+] to enter Span calibration.
• Press [N/-] to skip Span calibration and return to Zero
calibration.
• Press [MODE] to exit Span calibration and return to the top
calibration menu.
If you have pressed [Y/+] to enter Span calibration, then you will see
the name of your Span gas (the default is isobutylene) and the span
value in parts per million (ppm).
IMPORTANT!
If you are using the UltraRAE 3000 to test for benzene, it is
recommended that you calibrate with 5 ppm benzene calibration gas
from RAE Systems.
You will also see this message that prompts you:
1. Turn on your span calibration gas.
2. Press [Y/+] to initiate calibration.
Note: You may press [MODE] if you decide that you do not
want to initiate calibration. This will abort the span
calibration and take you directly to the Calibration menu for
Zero calibration.
3. Span calibration starts and displays this message:

20 Three-Point Calibration
For enhanced accuracy, it is possible to perform a second Span
calibration in addition to the Zero and Span calibrations outlined in
the previous section. Your instrument first must be set to allow this
third calibration. This requires using ProRAE Studio software and a
PC, as well as a higher concentration of calibration gas.
Note: Once the third calibration is set, you do not need to use
ProRAE Studio to allow future 3-point calibrations. Also, you can
only disable 3-point calibration capability by using ProRAE Studio
again.
Perform the Zero and Span calibrations. After the first Span
calibration (Span 1) is completed, the display a second Span
calibration (Span 2) can be performed. The process is identical to the
first calibration. As in the Span 1 calibration, you may exit and return
to the Zero calibration screen if you choose not to perform this
calibration or to abort it.

UltraRAE 3000 User’s Guide
20.1 Span 2 Calibration
A cylinder of standard reference gas (span gas) fitted with a 500
cc/min. flow-limiting regulator or a flow-matching regulator is the
simplest way to perform this procedure.
Note: This gas should be of a higher concentration than the gas used
for Span 1 calibration.
Choose the 500 cc/min. regulator only if the flow rate matches or
slightly exceeds the flow rate of the instrument pump. Alternatively,
the span gas can first be filled into a Tedlar bag or delivered through a
demand-flow regulator. Connect the calibration adapter to the inlet
port of the instrument, and connect the tubing to the regulator or
Tedlar bag.
Another alternative is to use a regulator with >500 cc/min flow but
allow the excess flow to escape through a T or an open tube. In the
latter method, the span gas flows out through an open tube slightly
wider than the probe, and the probe is inserted into the calibration
tube.
At the Span Calibration menu, you perform a Span calibration. You
may also go back to the Zero calibration menu or to the initial
Calibration menu if you want to exit calibration.
• Press [Y/+] to enter Span 2 calibration.
• Press [N/-] to skip Span calibration and return to Zero
calibration.
• Press [MODE] to exit Span calibration and return to the top
calibration menu.
If you have pressed [Y/+] to enter Span calibration, then you will see
the name of your Span gas (the default is isobutylene) and the span
value in parts per million (ppm). You will also see this message that
prompts you:
Please apply gas...
4. Turn on your span calibration gas.
58
UltraRAE 3000 User’s Guide
5. Press [Y/+] to initiate calibration.
Note: You may press [MODE] if you decide that you do not

a PC and transferred to the instrument. Note: The first gas in the
list is always isobutylene (it cannot be removed from the list).
• Last Ten is a list of the last ten gases used by your instrument.
The list is built automatically and is only updated if the gas
selected from Custom Gases or Library is not already in the Last
Ten. This ensures that there is no repetition.
• Gas Library is a library that consists of many of the gases found
in RAE Systems’ Technical Note TN-106 (available online at
www.raesystems.com).

cycle ranges from 50% to 100% (always on; this is the default value),
and the period is 10 seconds. Therefore, a duty cycle of 60% means that
the pump is on for 6 seconds and off for four seconds. Duty cycling is
employed by the instrument to clean the PID. A lower duty cycle has a
greater effect on keeping the PID clean than a higher duty cycle.
Important! Pump duty cycling is interrupted when the instrument
senses a gas. The pump’s duty cycle is disabled when the
measurement is greater than the 2ppm threshold and is re-enabled
when the reading falls below 90% of the threshold (1.8 ppm).

24.3 Optional Graphic Screen In Search Mode
Using ProRAE Studio, you can set your instrument to show a graphic
display instead of a numeric display of ongoing data. Consult your
ProRAE Studio disc for information.
During sampling, the display’s readings are shown numerically, plus
the graph tracks the highest readings over time. The numeric reading
alternates between the value and the measurement units, as well:

25 Advanced User Level (Hygiene
Mode Or Search Mode)
The User Mode called Advanced User Level allows a greater number
of parameters to be changed than Basic User Level. It can be used
with either of the Operation Modes, Hygiene Mode or Search Mode.
25.1 Advanced User Level & Hygiene Mode
With the instrument in Operation Mode: Hygiene Mode, enter User
Mode: Advanced User Level (refer to the section called Monitor
Mode for instructions).
Once you are in Advanced User Level and Hygiene Mode together,
you can change the calibration reference and measurement gas, in
addition to performing normal monitoring functions.
Pressing [N/-] progresses through the screens, while pressing [Y/+]
selects options. Pressing [MODE] makes menu choices when it is
shown for “Done” or “Back.” Pressing and holding [Mode] whenever
the circle with a vertical line in the middle is shown activates the
countdown to shutoff.

25.4 Diagnostic Mode
IMPORTANT! Diagnostic Mode is designed for servicing and
manufacturing, and therefore is not intended for everyday use, even
by advanced users. It provides raw data from sensors and about
settings, but only allows adjustment of pump stall parameters, which
should only be changed by qualified personnel.
Note: If the instrument is turned on in Diagnostic Mode and you
switch to User Mode, datalog data remains in raw count form. To
change to standard readings, you must restart the instrument.
25.4.1 Entering Diagnostic Mode
Note: To enter Diagnostic Mode, you must begin with the instrument
turned off.
Press and hold [Y/+] and [MODE] until the instrument starts.
The instrument goes through a brief startup, and then displays raw
data for the PID sensor. These numbers are raw sensor readings
without calibration. The instrument is now in Diagnostic Mode.
Note: In Diagnostic Mode, the pump and lamp are normally on.
You can enter Programming Mode and calibrate the instrument as
usual by pressing both [MODE] and [N/-] for three seconds.
You can enter Monitoring Mode by pressing [MODE] and [Y/+]
together for three seconds.
Once the instrument is started up in Diagnostic Mode, you can switch
between Diagnostic Mode and Monitoring Mode by pressing and
holding [MODE] and [Y/+] simultaneously for two seconds.
In Diagnostic mode, you can step through parameter screens by
pressing [MODE].

25.4.2 Adjusting The Pump Stall Threshold
If the gas inlet is blocked but the pump does not shut down, or the
pump shuts down too easily with a slight blockage, the pump stall
threshold value may be set too high or too low.
Use the following steps to adjust the pump stall threshold:
25.4.3 Pump High
In Diagnostic Mode, press the [MODE] key until “Pump High” is
displayed. The display shows the maximum, minimum, and stall
values for the pump at its high speed. Write down the “Max” reading.
Block the gas inlet and watch the pump current reading (labeled “I”)
increase. Write down its blocked reading. Note: If the pump current
reading does not increase significantly (less than 10 counts), then
there may be a leak in the gas inlet or the pump is weak or defective.
Add the two readings you wrote down. This is the average of the
maximum block count and the maximum idle count. Divide that
number by 2. Use the [Y/+] or [N/-] key to increase or decrease the
stall value to equal that number.
Press the [MODE] key to exit this display.
25.4.4 Pump Low
In Diagnostic Mode, press the [MODE] key until “Pump Low” is
displayed. The display shows the maximum, minimum, and stall
values for the pump at its low speed. Write down the “Max” reading.
Block the gas inlet and watch the pump current reading (labeled “I”)
increase. Write down its blocked reading. Note: If the pump current
reading does not increase significantly (less than 10 counts), then
there may be a leak in the gas inlet or the pump is weak or defective.
Add the two readings you wrote down. This is the average of the
maximum block count and the maximum idle count. Divide that
