I. GENERAL DESCRIPTION
The MiniBump is a small battery-powered, portable electrochemical gas
generator designed to functionally test and or calibrate toxic gas sensors
and alarm systems. The MiniBump is designed to 'bump' a gas detection
system into alarm within approximately 30 seconds when used with a
MiniBump generating source. When used with a MiniCal generating
source, the unit will provide calibration gas of the type and concentration
determined by the generating source to calibrate gas detection systems.
The MiniBump uses the following components to produce the calibration
gas/air mixture:
Internal Micro Pump
A small air pump draws in ambient air to blend with the
electrochemically generated gas. The Release IV MiniBump instruments
are designed to operate at .5 LPM (liters per minute).
Electrochemical Generating Source
The electrochemical generating source
contains an electrolyte solution and
either inert or consumable electrodes,
depending upon the gas being
generated. Gas is generated in the
solution and is delivered out of the
source by the internal pump, to the
detection system.
Alkaline 'A' Batteries
A set of two fully charged alkaline "AA"
batteries provides approximately
10-12 hours of operation. To replace the
batteries, open the battery cover with
eitherafingernailorsmallflatobject. Itis
importantthat whenchanging the
batteries in the instrument, to not use a
metal object, such as a screw driver.
Using a metal object toremove the batteries will frequentlyblow the pico
fuse in the unit, preventing the unit from powering up.

NOTE: Rechargeablebatterieswill provide
substantially fewer hours
of
operation andwillself-discharge whilethe instrument is instorage.
Users
should alsobeawarethatuseofrechargeable batterieswillvoid
the CSA approval of the MiniBump for intrinsic safety.
Microprocessor-Based Circuitry
Whenpowered-up,the microprocessorchecks for what type of generating
source is inserted, the gas type and concentration as well as if the
source is a “bump” type source and the remainingsourcelife. It also
monitors battery life and indicates when either a low battery or exhausted
source condition occurs. The circuit board is attached directly to the
bottom case via solder joints to the battery terminals. If damaged or
inoperable, it should be replaced as part of the case rather than removed
from these terminals.

7
II. START-UP MINIBUMP SOURCE
To start the generator, press and hold the ON/OFF Switch, located in the
middlefrontofthe instrument,untiltheGREENLEDturnson, approximately
3 seconds. Release the switchimmediatelythereafter.
The GREEN LED will blink at a rapid rate indicating the number of hours
of gas remaining in the source (5 blinks indicates 5 hours of life
remaining). It will then blink at a rate of once a second for approximately
20 seconds. Gas will begin to be generated immediately. After 20
seconds, the green light will stay illuminated and the pump will begin
running. With a bump source installed, the unit will run for an additional
20 seconds providing a ‘bump’ of output gas to drive the connected
sensor into alarm after which both red and green lights will alternate
indicating that the instrument is purging. It will shut off automatically
after an additional 25 seconds. Note: Some sensors have faster
response times than others. If the system does not respond to the gas
within30seconds,continuetoleave the MiniBump attached to the sensor
throughout the purge cycle and if needed, run the bump cycle a second
time.
If the RED LED begins flashing or remains lit continuously it indicates the
instrument is in either low battery condition or source failure mode.
Please refer to the section on Non-Normal Operation.

8
III. NORMAL OPERATION MINIBUMP SOURCE
The instrument is designed togenerate gas for approximately36seconds
per bump test. Each source will provide up to 1000 tests. The
MiniBump will generate gas until either the battery becomes discharged
or the source is consumed. If eitherconditionoccurs, aRED LED willlight,
indicatinganon- normal condition (refer to the Non-Normal Operation
section that follows.)
Thecalibrationgas is deliveredthroughasmallflexiblehoseattached to
thesourcemanifold cap. The hose is placed over, around or in frontof the
gas sensor. Alternatively, the detector can be placed directly in front of
the outlet fitting allowing the gas to be presented directly to the detector.

IV. START-UP MINICAL SOURCE
To start the generator, press and hold the ON/OFF Switch, located in the
middlefrontofthe instrument,untiltheGREENLEDturnson, approximately
3 seconds. Release the switchimmediatelythereafter.
The GREEN LED will blink at a rapid rate indicating the number of hours
of gas remaining in the source (5 blinks indicate 5 hours of life
remaining). It will then blink at a rate of once a second for approximately
20 seconds. Gas will begin to be generated immediately. After 20
seconds, the pump will come on and the unit will continue running with
the green light blinking for an additional 20 seconds. After this, the
green light will stay illuminated indicating the unit is ready to calibrate.
With a MiniCal source installed, the unit will continue to run in this state
generating the concentration and type of gas specified by the
generating source installed until turned off by pressing the power
button for an additional 3 seconds. When the unit is turned off it will
enter a purge cycle, both red and green lights will alternate indicating
that the instrument is purging. It will shut off automatically after an
additional 25 seconds. Note: Some sensors have faster response times
than others. Leave the MiniBump calibrator attached to the sensor until
the sensor has stabilized and then proceed with the calibration
procedure for that sensor.
If the RED LED begins flashing or remains lit continuously it indicates the
instrument is in either low battery condition or source failure mode.
Please refer to the section on Non-Normal Operation.

10
V. NORMAL OPERATION MINICAL SOURCE
The instrument is designed togenerate calibration gas at .5LPM (liters per
minute). Each MiniCal source will provide 5 hours of calibration gas.
The MiniBump will generate gas until either the battery becomes
discharged or the source is consumed. Ifeither condition occurs, a RED
LED will light, indicating a non-normal condition (refer to the Non-Normal
Operation section that follows.)
Thecalibrationgas is deliveredthroughasmallflexiblehose attached to
thesourcemanifold cap. The hose is placed over, around or in frontof the
gas sensor. Alternatively, the detector can be placed directly in front of
the outlet fitting allowing the gas to be presented directly to the detector.
When calibrating sample draw instruments, the output gas may be
collected into a gas collection bag. If this method is used, it is
recommended that the generated gas be allowed todiffuseinto a
calibration bag for several minutes to partially fill the bag. Be sure to
disconnect the sample draw unit before the bag is completely emptied of
calibration gas.

11
VI. NON-NORMAL OPERATION
If either the batteries or the generating source become depleted, or the
generating source is removed from the MiniBump, the instrument enters
a non-normal operating condition and the RED LED will turn on.
Under a low battery condition, the RED LED will begin to flash. If the
low battery condition occurs during power up, the RED LED will flash for
approximately 30 seconds and then the instrument will power down. If the
low battery condition occurs after start up, the RED LED will begin
flashing and the instrument willcontinuetorun forapproximately30
seconds before power down. It is recommended to replace depleted
batteries with two 'AA' heavy duty alkaline batteries for maximum
operating life.
If the source becomes depleted or is removed, the RED LED will light
continuously. If the depleted source condition occurs during power up,
the RED LED will remain on for approximately 30 seconds and then the
instrument will power down. If the depleted source condition occurs
after start up, the RED LED will light and the instrument will continue to
run for approximately 30 seconds before power down.
Ifthe sourcehas been
depleted, itshouldberemoved andreplaced
witha new generatingsource. Please refer to the section on source
life for proper
instructions on replacing the generating sources. If
the sourcehas not been depleted,there may be a faulty electrical
connection between the source and the instrument. Remove the
source and inspect the pins protruding from the source and the
sockets in the source chamber. Remove any debris and or corrosion
that may be present and retest the source. If either the pins or
sockets become damaged or non-repairable, replace the source
chamber and/or the source.

12
VII. CELL LIFE
The MiniBump generating source is consumed during normal
operation. All sources are rated for up to 1000 test maximum, 250
minimum. Once a source has been depleted, it may be replaced with a
new source to provide another 1000 tests. MiniCal sources last for 5
hours of use. Replacement sources may be stored in their containers in a
cool, humid area for several years under most conditions.
Different types of generating sources can be used with each instrument.
The microprocessor in the MiniBump reads the type of gas of the source
from a memory chip embedded in the source body. It then adjusts itself
for each type of gas output. For a complete list of correct source part
numbers, please refer to the parts list to follow.
To replace the generating source in the instrument, first remove the
instrument caplocatedonthetopofthe instrument. Thegeneratingsource
pulls directlyup out of the source chamber. Do not twist or rotate the
generating source while removing it from the source chamber or
damage may occur to either the source pins or the source chamber
sockets. The replacement source is replaced in reverse fashion. Care
must be taken when replacing the source to correctly line up the electrode
pins with the corresponding sockets. Do not force the sourceinto the
source chamber if it is not properlyaligned, otherwise thepins may
become damaged rendering the source and/or instrument useless.
NOTE: Never attach a sample draw instrument directly to the end of
the MiniBump delivery cup with no 'Y' or 'T' connector in between
the two instruments.

13
VIII. MAINTENANCE
The MiniBump instrument is designed to operate at 0.5 liters per minute
flow rate. For most accurate calibration when using a MiniCal source, the
flow should be checked and adjusted if necessary. Check the flow using
a volumetric flow meter connected directly to the output of the
instrument.
If the flow needs to be changed simply adjust the flow control
potentiometer until the correct reading is obtained. To access the
potentiometer simply remove the top cover of the instrument by pulling
up on the sides and the two halves will come apart exposing the internal
workings of the product. Replace the top cover and you are ready to
calibrate.
Changes in altitude and temperature can cause changes in air density,
thus affecting the output of the MiniCal source. The output was calibrated
to STP (standard temperature and pressure) of sea level and 20 °C. To
compensate for differences in altitude or temperature from STP, the
following tables should be utilized:
Note: Altitude and Temperature are cumulative, i.e., you must correct for
both factors to obtain the most accurate calibration.
