“ ” power key for more than six seconds when the

mete

r with the meter powered down. The second dis-

pla

ID has been set to 00.

To check the channel and ID of the meter:

Whe

n the meter is off press “ ” key and “ ” for

5 seconds. The LCD’s main display will show channel

number, the second display will show ID number.

2. NORMAL MODE

The following functions can only be used in the normal

mode.

(1) “ ” Power Button

The “ ” button turns the thermometer on or off.

Whe

n the meter is in MAX/MIN record mode, the

power off function is disabled.

uremen

t exceeds a specified limit. To set the limit val-

ues

, refer to limits function in the setup mode. Press

e [LIMITS] button to activate the limits function; the

word “LIMIT” should be displayed on the LCD.

Whe

n the value of the main display exceeds the Hi

limit

, the word “Hi” will be displayed and the ther-

momete

r will beep in a pulsed tone. If the value of the

mai

n display is lower then the Lo limit, the word “Lo”

wil

l be displayed and the thermometer will beep in a

continuou

s tone To exit the limits function, press the

data

; the word “READ” should be displayed on the

LCD

. To navigate around the save data table, press the

overla

y “SECOND” button until the “#” sign is dis-

playe

d on the second display. The location of the read

pointe

r within the saved data table will be displayed.

e arrow buttons on the overlay are used for scrolling

throug

h the saved data. Press the smaller arrows “ ”

or “ ” to step through the data one at a time. Press the

large

r arrows “ ” or “ ” to step through the data

n at a time. Pressing the overlay “ESC” button deac-

tivates the read data function.

(5) “LOG/READ” Button

The read log function works in conjunction with the log

function

functio

n can be activated in the shift mode. Press the

LOG/REA

D button to activate the log read function;

e word “READ” is displayed on the LCD. Press the

overla

y SECOND button to rotate through following

displa

y menus: T1, T2, GRP, and #. T1 and T2: Dis-

play

s the T1 or T2 saved data. GRP: Displays the cur-

ren

t group number. #: Displays the current location of

e read pointer within a selected group. The arrow

button

s on the overlay are used for scrolling through

e data and groups. Press the smaller arrows “ ” or

“ ” to step through the logged data or groups one at a

time

. Press the larger arrows

“

” or “ ” to step

throug

h the data or groups ten at a time. To navigate

SECON

D button until GRP appears in the second dis-

pla

y panel. Then select the group using the arrows.

Pres

s the SECOND button again until the “#” sign is

displayed

. The location of the read pointer in the se-

lected group will be displayed. Use the arrows to

scrol

l through the data. Pressing the overlay “ESC”

button deactivates the read data function

(7) HOLD Mode (only Main display)

When HOLD mode is selected, the thermometer holds

e present readings and stops all further measure-

ments

. To activate the data hold mode, press the

: The lowest measurement recorded. MAX-MIN:

e difference of the highest and the lowest measure-

ment. AVG: The average values of the measurements.

Thi

s mode works in conjunction with the hold func-

tion

, pressing the HOLD button will stop the recording

d measurements (Previously recorded readings are

t erased). Press HOLD button again to resume re-

cordin

g and measurements. To prevent accidental loss

of MIN, MAX and AVG data, the MIN/MAX function

n only be cancelled by pressing and holding down

e MIN MAX key for more then 2 seconds. The

men

t as the reference value, and “REL” should be

playe

d on the right part of the LCD. The next

uremen

t will display the current value compared
