The

the

 

DATALOGGER

 

icon

 

at

 

the

 

selected

 

sampling

 

rate,

 

indicating

 

that

 

readings

 

are

 

now

 

being

 

automatically

 

recorded

 

to

 

the

 

SD

 

card.

 

3.

 

If

 

a

 

card

 

is

 

not

 

inserted

 

or

 

if

 

the

 

card

 

is

 

defective,

 

the

 

meter

 

will

 

display

In

 

this

 

case,

 

switch

Pause

 

the

 

datalogger

 

by

 

pressing

 

the

 

LOG

 

button

 

momentarily.

 

The

 

DATALOGGER

 

icon

 

will

 

stop

 

flashing

 

and

 

the

rate

 

will

 

display

 

for

 

a

 

short

 

time.

resume

 

logging

 

simply

 

press

 

the

 

LOG

 

button

5.

 

To

 

terminate

 

the

 

datalogging

 

session

 

press

 

and

 

hold

 

the

 

LOG

 

button

 

for

 

at

 

least

 

2

 

seconds.

 

6.

 

When

 

an

 

SD

 

card

 

is

 

used

 

for

 

the

 

first

 

time

 

a

 

folder

 

is

 

created

 

on

 

the

 

card

 

and

 

named

 

MGA01

.

 

Up

 

to

 

99

 

spreadsheet

 

documents

 

(each

 

with

 

30,000

 

readings)

 

can

 

be

 

stored

 

in

 

this

 

folder.

 

7.

 

When

 

datalogging

 

begins,

 

a

 

new

 

spreadsheet

 

document

 

named

 

MGA01001.xls

 

is

 

created

 

on

 

the

 

SD

 

card

 

in

 

the

 

MGA01

 

folder.

 

The

 

data

 

recorded

 

will

 

be

 

placed

 

in

 

the

 

MGA01001.xls

 

document

 

until

 

30,000

 

readings

 

are

 

reached.

 

8.

 

If

 

the

 

measurement

 

session

 

exceeds

 

30,000

 

readings,

 

a

 

new

 

document

 

will

 

be

 

created

 

(MGA01002.xls)

 

where

 

another

 

30,000

 

readings

 

can

 

be

 

stored.

 

This

 

method

 

continues

 

for

 

up

 

to

 

99

 

documents,

 

after

 

which

 

another

 

folder

 

is

 

created

 

(MGA02)

 

where

 

another

 

99

 

spreadsheet

 

documents

 

can

 

be

 

stored.

 

This

 

process

 

continues

 

in

 

this

 

same

 

fashion

 

with

 

folders

 

MGA03

 

through

 

MGA10

 

(last

 

allowable

 

folder).
