Enable

 

the

 

Low

 

Alarm

 

if

 

you

 

want

 

an

 

alarm

 

to

 

trip

 

when

 

the

 

sensor

 

reading

 

falls

 

below

 

the

 

low

 

alarm

 

value.

 

Drag

 

the

 

slider

 

to

 

the

 

reading

 

that

 

will

 

trip

 

the

 

alarm

 

or

 

type

 

a

 

specific

 

reading.

 

5.

 

Set

 

the

 

duration

 

before

 

an

 

alarm

 

is

 

tripped

 

and

 

select

 

one

 

of

 

the

 

following:

 

 

Cumulative.

 

The

 

alarm

 

will

 

trip

 

once

 

the

 

sensor

 

reading

 

is

 

out

 

of

 

the

 

acceptable

 

range

 

for

 

the

 

selected

 

duration

 

any

 

time

 

during

 

logging.

 

For

 

example,

 

if

 

the

 

high

 

alarm

 

is

 

set

 

to

 

85°F

 

and

 

the

 

duration

 

is

 

set

 

to

 

30

 

minutes,

 

then

 

the

 

alarm

 

will

 

trip

 

once

 

the

 

sensor

 

readings

 

have

 

been

 

above

 

85°F

 

for

 

a

 

total

 

of

 

30

 

minutes

 

since

 

the

 

logger

 

was

 

configured.

 

 

Consecutive.

 

The

 

alarm

 

will

 

trip

 

once

 

the

 

sensor

 

reading

 

is

 

out

 

of

 

the

 

acceptable

 

range

 

continuously

 

for

 

the

 

selected

 

duration.

 

For

 

example,

 

the

 

high

 

alarm

 

is

 

set

 

to

 

85°F

 

and

 

the

 

duration

 

is

 

set

 

to

 

30

 

minutes,

 

then

 

the

 

alarm

 

will

 

only

 

trip

 

if

 

all

 

sensor

 

readings

 

are

 

85°F

 

or

 

above

 

for

 

a

 

continuous

 

30

minute

 

period.

Notes

 

about

 

alarms:

 

 

The

 

alarm

 

icon

 

will

 

be

 

illuminated

 

on

 

the

 

logger

 

LCD

 

when

 

the

 

alarm

 

trips.

 

You

 

can

 

also

 

press

 

the

 

Clear/Next

 

button

 

on

 

the

 

logger

 

to

 

view

 

the

 

farthest

 

out

of

range

 

value

 

during

 

the

 

deployment.

 

 

Alarm

 

limits

 

for

 

temperature

 

and

 

RH

 

sensors

 

are

 

checked

 

every

 

15

 

seconds.

 

The

 

CO

2

 

alarm

 

limits

 

are

 

checked

 

every

 

15

 

seconds

 

if

 

the

 

logger

 

is

 

powered

 

by

 

USB

 

cable

 

or

 

every

 

5

 

minutes

 

if

 

it

 

is

 

powered

 

by

 

batteries.

 

If

 

you

 

are

 

configuring

 

a

 

CO

2

 

sensor

 

alarm

 

for

 

a

 

battery

powered

 

logger,

 

it

 

is

 

recommended

 

that

 

the

 

duration

 

you

 

select

 

is

 

divisible

 

by

 

5

 

and

 

a

 

minimum

 

of

 

5

 

minutes.

 

 

For

 

USB

powered

 

loggers,

 

CO

2

 

alarms

 

will

 

not

 

be

 

tripped

 

for

 

the

 

first

 

15

 

seconds

 

after

 

logging

 

begins

 

as

 

the

 

CO

2

 

sensor

 

requires

 

a

 

15

second

 

warmup

 

period.

 

 

The

 

actual

 

values

 

for

 

the

 

high

 

and

 

low

 

alarm

 

limits

 

are

 

set

 

to

 

the

 

closest

 

value

 

supported

 

by

 

the

 

logger.

 

In

 

addition,

 

alarms

 

can

 

trip

 

or

 

clear

 

when

 

the

 

sensor

 

reading

 

is

 

within

 

the

 

resolution

 

specifications.

 

 

When

 

you

 

read

 

out

 

the

 

logger,

 

alarm

 

events

 

can

 

be

 

displayed

 

on

 

the

 

plot

 

or

 

in

 

the

 

data

 

file.

 

See

 

Logger

 

Events

.

 

 

Once

 

cleared,

 

an

 

audible

 

alarm

 

will

 

start

 

beeping

 

again

 

if

 

the

 

sensor

 

values

 

go

 

out

 

of

 

the

 

normal

 

range.

 

Even

 

if

 

an

 

audible

 

alarm

 

is

 

cleared,

 

a

 

visual

 

alarm

 

may

 

remain

 

on

 

the

 

logger

 

LCD

 

and

 

in

 

the

 

app

 

(if

 

applicable)

 

depending

 

on

 

the

 

settings

 

selected

 

for

 

maintaining

 

visual

 

alarms

 

or

 

because

 

the

 

alarm

 

condition

 

may

 

still

 

be

 

in

 

effect.

 

In

 

addition,

 

an

 

audible

 

alarm

 

will

 

continue

 

beeping

 

when

 

the

 

sensor

 

values

 

have

 

returned

 

to

 

the

 

normal

 

range

 

until

 

it

 

is

 

cleared.

 

 

Although

 

an

 

audible

 

alarm

 

and

 

a

 

visual

 

alarm

 

can

 

occur

 

at

 

the

 

same

 

time

 

when

 

a

 

sensor

 

alarm

 

is

 

tripped,

 

they

 

are

 

cleared

 

in

 

different

 

ways.

 

The

 

audible

 

alarm

 

can

 

be

 

cleared

 

from

 

within

 

the

 

software,

 

a

 

button

 

on

 

the

 

logger

 

is

 

pressed,

 

or

 

7

 

days

 

have

 

passed.

 

Meanwhile,

 

a

 

visual

 

alarm

 

is

 

cleared

 

as

 

determined

 

by

 

the

 

setting

 

selected

 

for

 

maintaining

 

an

 

alarm

 

in

 

the

 

software.

 

This

 

means

 

you

 

could

 

clear

 

a

 

beeping

 

audible

 

alarm

 

and

 

the

 

visual

 

alarm

 

will

 

remain

 

on

 

the

 

LCD

 

and

 

in

 

the

 

app

 

(if

 

applicable)

 

until

 

the

 

logger

 

is

 

reconfigured,

 

the

 

sensor

 

is

 

in

 

limits,

 

or

 

the

 

alarm

 

button

 

is

 

pressed

‐‐

whichever

 

setting

 

you

 

selected.

 

 

If

 

the

 

logger

 

was

 

configured

 

to

 

stop

 

logging

 

with

 

a

 

button

 

push,

 

any

 

tripped

 

alarms

 

will

 

be

 

cleared

 

automatically

 

when

 

logging

 

is

 

stopped

 

and

 

no

 

Alarm

 

Cleared

 

event

 

will

 

be

 

logged

 

in

 

the

 

data

 

file.

 

Burst

 

Logging

 

Burst

 

logging

 

is

 

a

 

logging

 

mode

 

that

 

allows

 

you

 

to

 

set

 

up

 

more

 

frequent

 

logging

 

when

 

a

 

specified

 

condition

 

is

 

met.

 

For

 

example,

 

a

 

logger

 

is

 

recording

 

data

 

at

 

a

 

5

minute

 

logging

 

interval

 

and

 

burst

 

logging

 

is

 

configured

 

to

 

log

 

every

 

30

 

seconds

 

when

 

the

 

temperature

 

rises

 

above

 

85°F

 

(the

 

high

 

limit)

 

or

 

falls

 

below

 

32°F

 

(the

 

low

 

limit).

 

This

 

means

 

the

 

logger

 

will

 

record

 

data

 

every

 

5

 

minutes

 

as

 

long

 

as

 

the

 

temperature

 

remains

 

between

 

85°F

 

and

 

32°F.

 

Once

 

the

 

temperature

 

rises

 

above

 

85°F,

 

the

 

logger

 

will

 

switch

 

to

 

the

 

faster

 

logging

 

rate

 

and

 

record

 

data

 

every

 

30

 

seconds

 

until

 

the

 

temperature

 

falls

 

back

 

to

 

85°F.

 

At

 

that

 

time,

 

logging

 

then

 

resumes

 

every

 

5

 

minutes

 

at

 

the

 

normal

 

logging

 

interval.

 

Similarly,

 

if

 

the

 

temperature

 

falls

 

below

 

32°F,

 

then

 

the

 

logger

 

would

 

switch

 

to

 

burst

 

logging

 

mode

 

again

 

and

 

record

 

data

 

every

 

30

 

seconds.

 

Once

 

the

 

temperature

 

rises

 

back

 

to

 

32°F,

 

the

 

logger

 

will

 

then

 

return

 

to

 

normal

 

mode,

 

logging

 

every

 

5

 

minutes.

 

To

 

set

 

up

 

burst

 

logging:

In

 

the

 

app:

 

Connect

 

to

 

the

 

logger

 

and

 

tap

 

Configure

 

in

 

HOBOmobile

 

or

 

tap

 

 

in

 

HOBOconnect.
