2. Check the peak value. Press Down key once to show peak

temperature, and the MAX LED will light up; press Down key again to

show the time stamp, i.e., the time when peak temperature is reached

(count from the start of the timer, unit is seconds), and the MAX LED

will flash. If the temperature continues rising, a new peak temperature

and its time will be written to the memory to replace the previous peak

value. Please see Section 9 for details.

3. Dimmer the display brightness. Press Up key to toggle the display

brightness between the dimmed display and the normal bright display.

The brightness of the dimmed display is determined by the parameter

"brit" described in the later section of the manual (see Section 7).

6. Alarm setting (code 0001)

The meter has two programmable alarms that can be set to turn on the

buzzer at specified temperatures. The alarm1 is controlled by

parameters AH1 and AL1; the alarm2 is controlled by AH2 and AL2.

These parameters can be accessed by code 0001 (see Table 1).

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 are set as a

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

low limit alarm. For a high limit alarm, the alarm buzzer should be on

once the temperature rise above AH, and it should be off only when the

temperature drops below AL. In contrast, for a low limit alarm, the alarm

buzzer should be on when the temperature drops below AH, and it

should be off only when the temperature rises above AL.

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

900, and AL1 = 800, the buzzer will go off once the measured

temperature is higher than 900° F; the buzzer will stop when the

temperature drops below 800° F. In another case, when AH2 = 180, AL2

= 185, the alarm2 is set as a low limit alarm. If the temperature drops

below 180° F, the buzzer will go off (on); when the temperature rises

above 185° F, the buzzer will stop.

User 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 instance, 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 disable 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

limit alarm at 480; alarm2 is disabled.

7. Alarm setting (code 0001)

The parameters for system configuration are listed in Table 1.

Table 1. System configuration parameters.

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 fluctuates 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

filtering effect. A strong filter increases the stability 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 dimmer). 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

brightness level 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.
