recalibrated after a cell change
2.3 Intrinsic Safety
The QUADRANT has been tested in Europe to current CENELEC standards, determined
to be intrinsically safe, and certified EEx d ia II C T4, which is equivalent to a Class I,
Groups A, B, C, and D rating in the United States. Use only the ni-cad battery pack
supplied by ENMET, part number 02601-006. The only alkaline batteries authorized to
use in the housing, ENMET part number 02602-012,are: Duracell MN1500LRG, Wonder
LR6, Varta 4006, Panasonic LR6AM3. Substitution of batteries or other components
may compromise the intrinsic safety of the instrument.
The QUADRANT has been tested and certified by the Canadian Standards Association to
CSA Standard C22.2 No. 152-M1984, Combustible Gas Detection Instruments. Under this
Standard, the performance of the combustible gas detection channel, only, is evaluated.
The QUADRANT has been examined and found in compliance with the European
directive relating to electromagnetic compatibility, and bears the mark in this regard.
3.0 Operation
3.1 Turn on/off
The instrument is turned on by pressing and releasing the ON/OFF button. Upon power
up, the instrument displays program version and goes through an internal test which takes
about 30 seconds. Then the display scrolls through the concentrations of each gas. There
is a confidence chirp and general alarm flash that activates about once every 60 seconds.
To turn the instrument off, press and hold the ON/OFF button for about 3 seconds. From
the scrolling display of gas measurements(see operation menu flow chart, page2) press
the + button to view date & time. By repeatedly pressing the + button the battery
information, minimum, maximum, STEL, and TWA measurements can also be viewed.
3.2 Alarms
The instrument display shows the peak value (or minimum, in the case of oxygen
deficiency) during any alarm condition, and latches until the Enter/Backlight button is
pressed. Factory set alarm points are 10% LEL methane, 19.5% and 23.5% oxygen, 35
PPM CO, and 10 PPM H2S.

3.3 Low battery alarm
When the battery approaches depletion and approximately 30 minutes use time remain, a
pulsating alarm sounds, the battery status display reads “DISCH”, and the audible and
visual alarms are acknowledgeable.
When the battery energy level is critically low, and battery failure is imminent, the
battery status display reads “DISCH”, and the instrument is in continuous visual and
audible alarm. The audible alarm is acknowledgeable but the visual is not. Recharge the
battery.
QUADRANT Instruments contain either a NiCAD or a NiMH battery. Charge bases are
not interchangeable. Be sure to place the instrument into the proper charging base.
Instruments and charge base with ATEX/Ex labels must be used together.
3.4 Auto-Zero
Auto-Zero or Auto-Set is a feature which allows the user to set the sensors and display to
read 0 ppm and %LEL for the toxic and combustible sensors, and 20.9% for the oxygen
sensor. It is done automatically when the instrument is removed from the charging base. It
can also be accomplished by entering the maintenance menu after the instrument has been on
for 10 minutes. Auto Zero should only be performed in a fresh-air environment!
3.5 Combustible Display
The instrument’s combustible sensor and associated display can be set to correlate with
any one of 25 pre-programmed gases and vapors. This is accomplished by starting with
the instrument turned off, pressing the + button and simultaneously pressing the ON/OFF
button and releasing them both. The display reads the currently programmed combustible
gas and can be scrolled through the entire list by pressing the + button repeatedly. When
the desired gas is displayed, press the Enter/Backlight button.
NOTE: The combustible sensor is non-specific and does not have the ability to distinguish
or be selective for a particular gas. Correct use of the instrument depends upon
the user’s knowledge of the application to identify which combustible gas to
display.
3.6 Data Logging
The QUADRANT can maintain sampling data in memory. The QUADRANT is capable
of data logging in intervals from one second to 15 minutes. Depending on the interval,
the storage duration ranges from 40 minutes to 600 hours. The normal 1 minute interval
yields a 40 hour duration period. The data logged into the QUADRANT is held in
nonvolatile memory so it is not lost when the instrument is turned off.
3.7 Downloading Data
Optional Maintenance COM 2000 software may be purchased from ENMET Corp. or an
authorized distributor. This software enables downloading the data kept in the
QUADRANT memory.

ENMET Corporation QUADRANT
4.0 Field Test the QUADRANT
To field test the QUADRANT, enter the operation menu, which is the scrolling display of
the gas measurements. Assure the correct field test gas is available, connect the
calibration adapter to the cylinder of gas and the QUADRANT calibration cover. Attach
calibration cover to instrument (aligning notch in cover with horn opening) and open
valve so gas flows gently over sensors. Apply gas for about two minutes, if instrument
goes into alarm in all channels which are turned on and gas supplied, it passes the field
test.
If instrument fails to go into alarm in any of the channels which are turned on and
gas supplied the instrument must be calibrated before use.
Note that if ENMET field test gas P/N 03299-000 is used, the H
S channel is not tested.

5.0 Maintenance
5.0.1 Scheduling QUADRANT Maintenance
It is recommended that all channels of a QUADRANT instrument be completely
recalibrated at least ever ninety days, utilizing the procedures given in this manual.
The sensor responses of an instrument should be checked at least every thirty days,
by exposing the sensors to appropriate gases and monitoring for expected instrument
response. Good practice dictates more frequent checking and calibration under
particularly dangerous conditions, conditions of heavy usage, and when the
electrochemical gas sensors are nearing the end of their useful lives. Some
instrument users check sensor responses at the beginning of every period of usage,
such as every shift. National, state, local, or company specifications may dictate
minimum calibration intervals. Check flammable sensor response after exposure to
more than 100% LEL of any flammable gas, and check electrochemical sensor
response after exposure to massive quantities of gas, such as 1000 ppm CO or 200
ppm H
S.

5.0.2 Maintenance Menu Entry
To enter the maintenance section use the preset password. The factory default password,
with which the instrument is shipped, is 1270. If this has been changed, per section 5.6,
use the correct password.
5.1 Auto-Zero
After instrument has been on for 10 minutes Auto-Zero or Auto-set is able to be done
from the maintenance section (see maintenance menu flow chart on page 3). This should
only be performed in a fresh-air environment!!
10
QUADRANT ENMET Corporation
5.2 Program
To program the QUADRANT, enter the program menu (see maintenance menu flow
chart on page 3). Select the channel to be programmed. Place the channel on or off
mode. The gas displayed on the combustible channel can be selected in this section (see
also combustible display). At this point the alarm point can also be set, or use the default
alarm point programmed in the instrument.
5.3 Calibration
5.3.1 To calibrate the QUADRANT
OTE: Always calibrate the Combustible sensor first.
N
Enter the calibration menu (see maintenance menu flow chart; maintenance functions on
page 3). The program is set to use the calibration gases supplied by ENMET and listed in
section 6, below. Assure that the correct calibration gas is available. Connect the
calibration adapter to the cylinder of gas and the QUADRANT calibration cover. Select
the channel to be calibrated and enter. Verify the calibration gas value and enter. Verify
the zero reading and enter. Attach calibration cover to instrument (aligning notch in
cover with horn opening) and open valve so gas flows gently over sensor. Wait for
reading to stabilize. Pressing the Enter button accepts the calibration. Pressing the –
button returns to the beginning of calibration menu without calibrating the instrument.
C
AUTION: Use only calibration gas during calibration, see Section 6.0. Do Not use field test
gas for calibration.
WARNING: Do not enter the calibration menu and attempt a calibration without a supply
of calibration gas.
5.3.2 Escape Calibration
Calibration of a channel, other than a oxygen channel, without calibration gas results in
an inoperative channel; and displays “GAS used” for that channel.
If in the calibration menu, and calibration gas is not available:
•At the zero stabilization prompt, 0:XXX, or the span stabilization prompt, S:XXX, press
the – button; the display returns to “calib.”
•At the span stabilization prompt, when the
ENTER button is pressed, “GAS used” is
displayed. Do not press the enter button again, instead press the – button, the display
returns to “calib.”
If at “GAS used”, the ENTER button is pressed, the “GAS used” fault alarm is on
continuously for that channel. Disable the channel if it is necessary to use the other
channels; note that there is no detection capability for the disabled channel. Obtain the
calibration gas, enable the channel, and go through the sensor replacement procedure,
section 5.4, without actually changing the sensor; note that this procedure includes
recalibration.

should be done with the spring-mounted belt clip in the “open” position. Allow the clip to snap in
place over the top of the harness pad as the instrument slides down into place. This will secure the
instrument firmly in the harness/holster assembly.

Returning an Instrument for Repair
ENMET instruments may be returned to the factory or any one of our Field Service Centers for
regular repair service or calibration. The ENMET Repair Department and Field Service Centers
also perform warranty service work.
When returning an instrument to the factory or service center for service, paperwork must be
included which contains the following information:
¾ A purchase order number or reference number.
¾ A contact name with return address, telephone and fax numbers
¾ Specific instructions regarding desired service or description
of the problems being encountered.
¾ Date of original purchase and copy of packing slip or invoice
for warranty consideration.
¾ If a price estimate is required, please note it accordingly and be
sure to include a fax number.
Providing the above information assists in the expedient repair and return of your unit.
Failure to provide this information can result in processing delays.
ENMET charges a one hour minimum billing for all approved repairs with additional time billed
to the closest tenth of an hour. All instruments sent to ENMET are subject to a minimum $30
evaluation fee, even if returned unrepaired. Unclaimed instruments that ENMET has received
without appropriate paperwork or attempts to advise repair costs that have been unanswered,
after a period of 60 days, may be disposed of or returned unrepaired COD with the evaluation
fee.
Service centers may have different rates or terms. Be sure to contact them for this
information.
Repaired instruments are returned by UPS/FedEx Ground and are not insured unless
otherwise specified. If expedited shipping methods or insurance is required, it must be
stated in your paperwork.
Note: Warranty of customer installed components.
If a component is purchased and installed in the field, and fails within the warranty term,
it can be returned to ENMET and will be replaced, free of charge, per ENMET’s returned
goods procedure.
If the entire instrument is returned to ENMET Corporation with the defective item
installed, the item will be replaced at no cost, but the instrument will be subject to labor
charges at half of the standard rate.
