Ⅰ. Features ● Sensor unit is equipped with 2 thermocouples to detecting the

temperature change of environment, water or soil at the same

time.

● Temperature alarm function to alert the temperature is

beyond the range set by the user.

● K-type temperature range: - 200°C ~ +1370°C

● Main unit and sensor unit each has 8 identity codes (1 ~ 8

and I.D. for short). The I.D. provides the protection from

interference of transmission where have two sets or more

thermometer using at the same time in the same radius area.

● Audible alarm of main unit alerts 4 possible status –

1.Battery power is low at main unit or sensor unit.

2.Temperature is over the range set by the user.

3.Transmission is disconnected.

4.In measuring mode but main unit displays “no”.

Temperature

1. Check battery power of main unit and sensor unit before

using. Do not place sensor unit and main unit from each other

over the limit distance to prevent the fail transmission. And

keep away from the interference objects or signals.

2. The limit distance between main unit and sensor unit is

typically 100M (330 feet) in open space.

3. The distance between main unit and sensor unit is shorter

than 100M while there are barriers between the set up

positions of units. The optimum distance depends on the

material of barrier or the construction of building.

4. Do not put sensor unit into fridge or the metallic sealed

equipment (enclosure) directly for measurement. Because the

signal of sensor unit is blocked and can't transmit to main unit

successfully.

5. For measuring fridge temperature only put the thermocouple

wire tip in fridge.

6. A & B input socket (A → as CH1 on main unit display and B →

as CH2) can take 2 K-type thermocouples for measurement.

Apply the different temperature range of K-type thermocouple

to work with the need. The applicable range is -200°C ~

+1370°C.

7. Set up I.D. of sensor unit

※ 8. Install batteries -– always install main unit first and complete

I.D. set from panel keys and then install batteries into

sensor unit and complete I.D. set from switch in battery slot.

The I.D. code of main and sensor unit should be the same.

9. To ensure the data to be captured by the main unit the initial

transmission from sensor unit acts aggressively by every 6

seconds once set up. After the 9th data, the transmission of

sensor unit and the receiving of main unit is parallel

corresponding to each other.

Attention: do not attempt to

loose those 2 screws.

affect the transmission.

● In extreme high or low temperature environment, the

transmission may be slow or creeping.

● Besides battery door, please do not attempt to loose other

screws in order to make sure the thermometer operates in

good condition.

● Take the batteries out of the thermometer if it will be left idle

(A). Battery installation

Always install main unit first and then sensor unit. Follow

instruction of A & B as below to enable transmitting and

receiving in good work.

1. Battery (alkaline) life time for main and sensor unit is one

year round which mainly depends on the application in

different temperature and environment. Use 2 AA size

alkaline batteries each for main and sensor unit.

2. Battery life time depends on the working condition. Such

as repeat search for signal (because of interruption) or

frequent alarm will cut down the battery life time. Need

to replace the new batteries while the low battery symbol

(sensor unit) or (main unit) display.

3. Do not attempt to loose the screws marked on drawing.

4. Main unit has no power switch and can be power off from

removing batteries exclusively.

5. Contact the maker or deliver the thermometer back to the

maker for checking if it can't work after the batteries

installation process is completed.

B. Battery installation of sensor unit

Follow the steps from dwg#1 to dwg# 7 to complete the

installation.

(1) Loose 2 screws on battery door with Philips screw driver.

(2) Do not attempt to loose 4 crews marked on dwg#2.

(3) Choose I.D. by changing the switch in the battery slot before

installing batteries. I.D. code from 1 to 8 (refer to page 6

(C)-7.). The I.D. should be the same as the main unit for

transmitting and receiving recognition.

(4) Fasten screws on battery door after installing batteries.

(1.5V AA size battery * 2) Be sure to put with the correct

polarity as marked in the slot.

(5) After battery installation, the light on sensor unit is flashing to

identify I.D. Then the light is flashing every 6 seconds and

transmitting the data of each flashing. After the 9th data, the

transmission of sensor unit and the receiving of main unit is

corresponding to each other and go into regular cycle by

transmission/receiving every 3 minutes. Each flash of light

means transmission is working and main unit refresh display

of CH1 & CH2 every 3 minutes as well.

(6) In 1 minute after battery installation, check main unit if

display any reading of temperature from sensor unit. If not,

please make sure if I.D. of main and sensor unit is the same.

And check if batteries are well installation and light is

flashing during transmission of data. If all those are positive

but still can’t find any reading on main display, please

contact the maker for problem remove or deliver the

thermometer back to the maker for checking.

2. Once batteries are installed the full segment will display on LCD

for 2 seconds.

Check the battery installation is correct or not If can't shift the

display from (1) to (3). If the installation is surely correct

please contact the maker for problem remove or deliver the

instrument back to the maker for checking if necessary.

(B). Set up I.D. (identity code)

Choose I.D. of main unit:

Push MODE & MAX/MIN keys simultaneously for 3 sec. until

display and flashing. Push MAX/MIN key to choose

I.D. code from 1 to 8. Push MODE key to complete setting

after chosen.
