USER’S GUIDE

Chapter 1. Overview

Thanks for using the thermometer of ME-SP33X series by Sure Electronics. Please read this manual carefully prior to the installation of thermometer. Thermometers of ME-SP33X series are the first LED-based self-made type. Aside from the features such as simplicity, self-adaptation to ambient brightness inherited from panel meter of ME-SP03X series, flexibility is the most impressive feature which provides 4 different versions that can suit the needs of global buyers.

TABLE 1-1 MEMBERS OF ME-SP33X SERIES

ME-SP33X SERIES

Thermometers equipped with built-in sensor , su ch as ME-SP330 and ME-SP332, can be used to measure temperature in household families, offices, PC rooms and vehicles. While external probe can help you extend your application range to some harsh environment, such as to measure the water temperature of vehicles, air-conditioners, refrigerators, water-heaters or the temperature of computer cases since the external probe itself is water-proof. As listed in the above table, ME-SP330 and ME-SP331 are equipped with a single built-in sensor and an external probe respectively. While ME-SP332 and ME-SP333 can measure temperature of two different applications since both of them are equipped with dual sensors.

Chapter 3. Features

The brightness of the diode varies with the change of ambient brightness and won’t be too dazzling in night time.

3.1 Adapted to the Ambient Brightness

1. The brightness of diode will reach its topmost when the panel meter is in a room under direct sunlight exposure.

USER’S GUIDE

2. The brightness of the diode is comparatively high when the panel meter is placed in a room, around which the environment is similar to dawn, nightfall or cloudy weather.

ME-SP330 & ME-SP331 & ME-SP332 & ME-SP333_Ver1.0_Page 4

0.56" Digital Red LED Automobile Thermometer Panel Meter

3. The brightness of the diode is the darkest when the panel meter in placed in an environment of almost no light from outside.

3.2 Slowly Adjust the Brightness of Diode

Features

When the ambient environment of panel meter is shifted from light to dark or dark to light, the brightness of diode will be gradually changed and whole process will la st for 1 seconds. The adjustment of brightness is smooth and it won’t make people feel abrupt.

Chapter 4. How to Use a Thermometer

4.1 Connection with Power Supply and Thermo Probe

FIGURE 4-1 CONNECTION SCHEMATIC

USER’S GUIDE

Note:

1. “VCC (+)” and ”GND (-)” shall be connected with the positive (+) and negative (-) of DC power supply ranging from 8.5-26V.

2. Pay more attention to polarity when hooking up, otherwise thermometer will be burnt out.

3. When an external probe (no matter a 2-pin or 3-pin version) is to be connected with the pin header of thermometer, always leave the pin “+5V” disconnected.

4.2 Display Mode Settings

4.2.1 Display in ℉&℃

Thermometer can display temperature in ℉or℃, which can be set by K1 and K2 of DIP switch.

K1 K2 Func. OFF OFF ON OFF OFF ON ON ON No function

Notes:

1. By setting K1 and K2, thermometer can alternately display temperature in ℉ and ℃.

Display in℃ Display in ℉ Alternate display with the change of ambient brightness（℉/℃）

ME-SP330 & ME-SP331 & ME-SP332 & ME-SP333_Ver1.0_Page 7

How to Use a Thermometer

2. See following for steps of how to make the thermometer change its display from C(F)to F(C) with the change of ambient brightness C(F)to F(C): ① Expose thermometer under intense light source (luminance intensity >=1000

Lux).

② Cover thermometer with something to avoid being exposed under intense light

(luminance intensity<=60Lux).

③ Thermometer will start to change the current display from ℃(℉) to ℉(℃) if

you repeat the above steps twice.

Application example:

You will need a flashlight to toss light directly on thermometer when ambient luminance intensity is less than 60 Lux and normally you will need to repeat the on & off action twice. You can also use flashlight even when the ambient luminance intensity exceeds 60 Lux, when you switch off the flashlight, cover your thermometer with your hands so that the luminance intensity can fall short of 60 Lux.

4.2.2 Select Display Temperature from CH1 or CH2

Thermometer allows you to select displaying temperature reading from CH1 or CH2, which can be achieved by setting k3 and k4 of DIP switch.

K3 K4 Func. OFF OFF Display temp reading of CH2 ON OFF Display temp reading of CH1 OFF ON Alternate displaying automatically ( CH1 / CH2) ON ON

Notes:

1. Set K3 and K4 to OFF in terms of ME-SP330.

Alternate display with the change of ambient brightness(CH1 / CH2)

0.56" Digital Red LED Automobile Thermometer Panel Meter

2. Set K3 and K4 to ON and OFF respectively in terms of ME-SP331.

3. In terms of ME-SP332 and ME-SP333, thermometer can alternately display temperature of CH1 or CH2 by setting K3 and K4.

4. Thermometer will display temperature reading of CH2 if it were selected to do so.

5. Thermometer will display temperature reading of CH1 if it were selected to do so.

6. When you select to display temperature readings of both CH1 and CH2 automatically and alternately, thermometer will do so.

Details are as follows:

① Time interval for each change in between CH1 and CH2 is 4 seconds. ② The displaying of CH1 and CH2 denotes the temperature displaying thereafter.

CH1 means temperature reading from CH1 will be displayed and CH2 means temperature reading from CH2 will be displayed.

7. When Alternate display with the change of ambient brightness is selected, you can have thermometer display temperature readings of CH1 and CH2 alternately by changing the ambient brightness.

Detailed steps are as follows:

① Expose thermometer under intense light (make luminance intensity >=1000

Lux).

② Cover thermometer with something to avoid intense light (make luminance

intensity <=60 Lux).

③ Repeat the above steps four times and thermometer will change the current

display from CH1 (CH2) to CH2 (CH1).

④ It takes approximately 9 seconds before the next prompt(CH1/CH2) can be

displayed when the thermometer is in use. The display of CH1(CH2) denotes the display of temperature readings from CH1(CH2).

Application example: refer to 4.2.1
