Proster PST095 Digital Dual Channel Thermometer Instruction Manual

Proster PST095 Digital Dual Channel Thermometer

NOTE:
Our K-type thermocouple can measure 0~250℃(300℃ in a short time). Please do not test objects over 250℃ with it. If you need to test objects over 250 °C, please purchase the appropriate K-type thermocouple by yourself.

Introduction

Thermocouple is one of the most commonly used industrial elements in temperature measuring which is formed when 2 dissimilar metals are joined as a circuit with thermo current generated from the temperature difference between the metals. If there is any temperature difference between the thermocouple tip and the reference end of the thermocouple, the instrument will display the temperature value versus the thermo emf generated from the thermocouple. On- site measurement and long-distance transmission can both be carried out. This device can measure the temperature of the liquid/vapours and surface temperature of a solid object, with a considerably wider measuring range than those of mercury thermometers and alcoholometers. It is suitable to be used both in the high-temperature fields of blast furnaces and cookery and the low- temperature measuring for liquefied hydrogen and liquefied nitrogen etc.

Features

1. High accuracy: due to direct contact with the measured without intermedia which affects the final output.
2. Convenient operation.
3. Unit Celsius and Fahrenheit unit.
4. Data hold and MAX、MIN、AVG.
5. Human-centered design, easy operation.
6. Double display with backlight shows T1/T2 and a combination of T1 and T2.
7. To measure the thermocouple of J, K, T, E, N and R type.
8. The electrical compensation function provides the compensation for the thermocouple error to improve the overall precision.

Warning & Cautions

A Warning identifies conditions and actions that pose hazards to the user. To avoid electrical shock or personal injury, follow these guidelines:

• Before using the thermometer inspect the case. Do not use the thermometer if it appears damaged. Look for cracks or missing plastic. Pay particular attention to the insulation around the connectors.
• Disconnect the thermocouple(s) from the thermometer before opening the case.
• Replace the batteries as soon as the battery indicator“ ”appears. The possibility of false readings can lead to personal injury.
• Do not use the thermometer if it operates abnormally. Protection may be impaired. When in doubt, have the thermometer serviced.
• Do not operate the thermometer around explosive gas, vapour, or dust.
• Reflective objects result in lower than actual temperature measurements. These objects pose a burn hazard.
• Do not connect to voltages >30 V ac rms, 42 V pk, 60 V dc from earth ground.
• Measurement errors may occur if voltages on the measurement surfaces result in potentials greater than 1 V between the two thermocouples. When potential differences are anticipated between the thermocouples, use electrically insulated thermocouples.
• Use the proper thermocouples, function, and range for your thermometer.
• Do not attempt to recharge the batteries.
• Do not throw batteries into a fire to prevent an explosion.
• Match the + and − polarities of the battery with the battery case.

7. Press the key until there is an AVG icon appearing on the LCD together with the average reading.
8. Repeatedly press the key to show the readings in the sequence above.

Option of thermocouple type
Press the TYPE key to switch the type of thermocouple in a sequence of K-J-T-E-R-N-S for option.

Switch between T1/T2 &T1-T2
The following information in sequence repeatedly: main display T1 & auxiliary display T2>main display T2 & auxiliary display T1>main display T1-T2 & auxiliary display T2.

Backlight
Press any key to activate the backlight. The backlight will be turned off automatically within 30 seconds if there is no further operation on the key.

Automatically turn-off
To save power the device will be turned off automatically if there is no operation on the key within 1 minute. To close this function, hold on pressing the HOLD key to activate the device and there is no “ ” displaying on the LCD, and can only manual power-off be used. After powering off the device again, this auto-turn-off function will be cancelled again.

battery replacement
when the “ ” flashes on the LCD indicating the insufficient battery, replace the old ones with 3 fresh 1.5V AAA batteries
