AH1 and AH2 are called alarm on temperature, i.e. the temperatures at which the

Alarm1 and Alarm2 will turn on; AL1 and AL2 are called alarm off temperature, i.e. the

temperatures at which the Alarm1 and Alarm2 will turn off. When AH1>AL1(or

AH2>AL2), the alarms is set as a high limit alarm. When AH1<AL1(or AH2<AL2), the

alarm is set as a low limit al a rm. For a high limit alarm, the alarm buzzer shoul d be on

once the temperature ri s e above AH, and it should be off only when the temperature

drops below AL. In contrast, for a low limit alarm, the alarm buzzer shoul d be on when

the temperature drops below AH, and it should be off only when the temperature rise

above AL.

For example, when the temperature unit is set to F (Fahrenheit), AH1=900, and

AL1=800, the buzzer wil l go off once the measured temperature is higher than 900° F;

the buzzer wil l stop when the temperature drops below 800° F. In another case, when

AH2=180, AL2=185, the alarm2 is set as a low limi t alarm. If the temperature drops

below 180° F, the buzzer wil l go off (on); when the temperature rises above 185° F, the

buzzer will stop.

Users can press the Shift key ( > ) to mute the buzzer. The alarm will buzz again if the

alarm temperature moves out of the alarm zone (between AH and AL) and re-enters it

again. For i n stance, AH1=900, AL1=800, current temperature is higher than 900, and

the alarm is muted. In this case, the temperature has to drop below 800 and rise

above 900 again to trigger the alarm buzzer. To di s abl e the alarms, set AH and AL to

the same value, i.e., AH1=AL1 and AH2=AL2.

Steps to set an alarm are described below as well as in the flow chart in Figure 4:

(1) Press SET key, change the code to 0001, and press SET again to enter alarm

setting mode.

(2) Press Up and Down key to select a parameter (AH1, AL1, AH2, or AL2).

(3) Press SET to view the value of the parameter.

(4) Use Shift, Up, and Down key to change the val u e.

(5) Press SET key to confi r m the value and exit from this parameter.

(6) Press Up or Down key to select the new parameter.

(7) To exit this mode, press SET key when End is displayed.

The procedure is showed in the flow chart in Figure 4.

Note 1. Inty (Input sensor type). This parameter defines the sensor type that is used for

the thermometer. If you purchased the thermometer bundle, it is already set for the

probe included in the package. You don t need to change it.

Note 2. PSb (input offset). This is to set an offset value to compensate the error

produced by the sensor. For example, if the meter displays 5 ºC when probe is in ice/

water mixture, setting PSb= -5 will make the meter display 0 ºC. You can use shift key

(second key from the left) to shift to the first left digit, then press down key once to enter

minus sign.

Note 3. FILt (digital Filter). If the temperature reading fl u ctuates due to input noise, a

digital filter can be used to smooth the input signal. FILt may be configured in the

range of 0-3. Higher the value, stronger the fi l tering effect. A strong filter increases the

stabi l ity of the readout, but causes longer delay in responding to the temperature

change. Set FILt=0 will disable the filter.

Note 4. C-F (temperature unit). Set to C if you want to display temperature in Celsius.

Set to F for Fahrenheit.

Note 5. Brit (display di m mer). This parameter sets the brightness level of the dimmed

LED display. You can switch the LED brightness level between the dimmed and the

normal using UP key. However, the normal bri g htness l e vel of the LED display is equal to

level 4. So if Brit is set to 4, you won t see and change in the brightness of LED display

when pressing UP key.

Note 7. Baud (Baud rate for communi c ation). This should be left as default.

Note 8. Id (Unit ID). Each slave unit should be assigned with a unique Unit ID. The

default value is 1. The value of the Unit ID can range from 0 to 240. A master unit can

communi c ate with up to 10 slave units. For example, if you have two slave units, you can

set their Unit ID to 1 and 2 respectively. Then, when the master Unit ID is set to 1, it will

read the temperature of slave unit 1. When the master Unit ID is set to 2, it will read from

slave unit 2. Set two slave units to the same ID number will cause crashes.

Note 9. tdly (Hand shake ti m e). This is the time interval (unit i n seconds) after which the

master unit will attempt to read signal from the slave unit again. If the master unit

receives signal during this hand shake time, it will refresh and display the current reading

at the assigned cycle rate. Otherwise, it will display the previous reading for the rest of

the current hand shake cycle. If there is still no signal received during the entire hand

shake time, the master unit wil l display four dashes ( - - - - ). This setting can prevent the

master unit from frequently switching between temperature reading and four dashes. If

the master unit and the slave uni t is far away from each other or the signal is weak, user

should increase the hand shake time. Placing the master and slave unit too close to each

other may also result in no readi n g on the master unit.

Note 10. tACy (Sampling rate). This parameter sets how frequently the slave unit refresh

its reading . The default sampli n g rate is 1 per second. The unit is s
