SETTING DATE AND TIME

With the analyzer running, press the Func Key repeatedly to access the
date/time screen. From this function Time, Date and Year can be changed.

If the Date and Time do not need to be changed, press the Func Key to
bypass this function and return the 712 to combustion analyzer mode
(Function 1).

1. Once the Time, Date, and Year screen is displayed, press the Scroll/Enter

Key once to allow you to change the data.

2. Press the Up Arrow Key to Increase the Minutes.

3. Press the Down Arrow Key to Decrease the Minutes.

4. Press the Scroll/Enter Key to confirm the desired Minute and move onto

the Hours.

5. Repeat steps 2 to 4 to change the Hour, the Day, the Month and the Year.

6. The unit will return to normal after the desired Year has been confirmed

Thermometer Mode

With the analyzer running, press the Func Key to access the thermometer
function. In this mode the 708 functions like a K-Type thermocouple ther-
mometer. The pump will stop running when in this function.

1. Ensure you have a 'K' type probe connected to one or both of the thermo-
couple sockets T1 or T2 (refer to figure below)

WARNING

: - There is ONLY one correct way to connect the 'K' type thermo-

couple plug into the socket (see page 7). Forcing the plug into the socket the
wrong way may result in damage to the instrument.

2. Touch the temperature probe to the item under test and read the displayed
temperature.
Other Features:

• Pressing the Up Arrow Key will toggle between ºC and ºF
• Pressing the Scroll/Enter Key will toggle the Differential Temperature ON 
and OFF
• Single Log Mode (S-Lg) can be activated to log temperatures. See section
10.
• 'oPEn' will be displayed if no 'K' type probe is connected to the thermocou-
ple socket

The thermometer func-
tion allows you to per-
form temperature tests.
