GENERALDESCRIPTION

TheSensit®HCNisanadvancedstate-of-the-artHydrogenCya-

nide (HCN) gas analyzer designed to provide part per million

readingsfrom 0-100ppm. TheSensit®HCN iscapable ofper-

forming ambient as well as hot or smoldering air samples with

itshot airprobe andpowerful rotaryvane pump.

TheSensit®HCNisequippedwithan advancedlonglifeelectro-

chemical sensor that can be field calibrated and has a low re-

placement cost. Arenewable filter eliminates cross sensitivity

to many gases.

TheSensit®HCNmayalsobeusedasapersonalmonitor.There

is an alarm at 5ppm. The display must be in view to determine

gasconcentrations.

oxide sensor (CO) to simultaneously monitor from 0-2000ppm

BATTERYINSTALLATION/REPLACEMENT

Battery replacement is necessary when thedisplay reads BAT

LOW,anaudiblealarmsoundsandthegreenreadyLEDflashes.

WhenBAT LOW isdisplayed,theinstrument hasapproximately

30minutes of useful operationtime prior toshut off.

CAUTION: Always change batteries in an environment

free of combustible gases.

Removethe batterysleeve coverby depressingthe lockingtab

onthefront ofthehandle withacoinorflat objectandpulling the

handle away from the top or display area of the instrument.

Place 3 approved batteries into the battery holder. For best

resultshold thebatterycompartment sothat itlays inyour right

hand. With your left hand install the battery that goes toward

the front first. The battery that is in contact with the rear spring

secondand finallyinsertthe thirdbatteryin thecenterby forcing

thesecond batterysuch thatthe springcompresses andallows

the batteries to go into place. If you do not use your right hand

tohold thebottom ofthe batterycompartment thebatteries can

come out.

Observethepolaritymarkings ontheinsideofthe batteryholder.

Improper installation will cause the instrument not to operate.

Replace the battery sleeve and allow the locking tab to snap

into position.

Checkto besurethe handleis securetothe instrumentbody by

gently pulling the handle away. The handle will remain firmly in

place if a proper connection is made.

OPERATION AND USE continued from page 6

4. Prior to use, use your finger to block the inlet of the instru-

mentfor 4-5seconds. Thedisplay willread “FLOWBLOCKED”

if all seals are intact. During pump flow block, a beep will occur

every 2 seconds until the pump restarts and adequate flow is

present.

CAUTION: Always operate this instrument with Filter

Kit or the High Temperature Probe installed. This will pre-

vent water or debris from damaging the internal pump.

5. When testing areas with elevated temperatures always at-

tach the optional hot air probe assembly. Attach the probe by

twistingtheconnector oftheprobeontothe matchingadapterat

theend of the instrument

These connections need only be finger tight. It is necessary to

use a particle filter when performing flue testing. The use of an

unapprovedprobe assemblymayvoid thewarranty.

CAUTION: Do not handle the steel portion of any hot

air probe after use as burns may occur!

CALIBRATION

From the menu options, it is possible to calibrate the sensor in

the Sensit®HCN instrument. Calibration is the process of set-

tingthe readingsofthe instrumentto certifiedcalibration gases.

When calibrating, the numbers shown on the display rep-

resent the numbers seen by the microprocessor. These

readings should not be confused with actual gas readings.

Prior to any calibration, power the instrument in a gas free

environment. Allow 5 minutes of additional warm-up time and

manuallyzerotheinstrumentusing theSAVE/ZERO(C)button.

STEP 1

From the working display access the menu by pressing and

holding the MENU (B) button until the top line of the display

reads USER MENU. Press and release the SAVE/ZERO (C)

buttonuntil thebottom linedisplaysCALIBRATION. Press the

MENU(B). The toplinewill nowread CALIBRATION.

HYDROGENCYANIDE(HCN)CALIBRATION (HCN 10PPM)

To calibrate HCN, push the MENU (B) when the top line reads

CALIBRATION andthe bottomline readsHCN10 PPM. Imme-

diately apply 10 ppm HCN.

When the reading is satisfactory, the display will read DATA

SAVED indicating calibration is complete. The date for CAL

PAST DUE is automatically reset at this point. Pressing the

POWER/MUTE(A)button willreturnthe instrumenttothe work-

ing(gas readings) display. Removethe gas.

CALIBRATION continued from page 15

CARBONMONOXIDE (CO) CALIBRATION(CO - 100PPM)

To calibrate CO, push the MENU (B) when the top line reads

CALIBRATION andthebottom linereads CO100 PPM. Imme-

diatelyapply 100 ppmCO (balanceair).

When the reading is satisfactory, the display will read DATA

SAVED indicating calibration is complete. The date for CAL

PAST DUE is automatically reset at this point. Pressing the

POWER/MUTE(A)button willreturnthe instrumenttothe work-

ing(gas readings) display. Remove thegas.

NOTE:Improper calibration is indicated by “Bad Cal” when

save is attempted. Calibration will be based on the last

successfulcalibration. Recalibration is recommended. The

calibration due date will not be updated until successful

calibration has occurred. Any instrument that does not

calibrate requires service. Contact SENSIT Technologies

for details.

CAUTION: Using calibration kits other than the recom-

mended kit may cause inaccurate readings. Repairs are

required if any sensor fails to calibrate. Contact manufac-

turer for details.
