Setup

Battery Installation:

The Protmex YT606 requires 4 AAA batteries (included). Follow these steps to install them:

Locate the battery compartment on the back of the device.
Use the included screwdriver to open the battery compartment cover.
Insert 4 AAA batteries, ensuring correct polarity (+/-) as indicated inside the compartment.
Replace the battery compartment cover and secure it with the screw.

A low battery indicator will appear on the LCD screen when the batteries need to be replaced.

Operating Instructions

Power On/Off:

Press the Power button (①) to turn the device on.
Press and hold the Power button (①) for a few seconds to turn the device off.

Measurement Modes:

The YT606 offers four primary measurement modes:

Ambient Temperature: Displays the current air temperature.
Relative Humidity (RH): Shows the percentage of moisture in the air relative to the maximum amount it can hold at that temperature.
Wet Bulb Temperature (WB): The temperature read by a thermometer covered in water-soaked cloth over which air is passed.
Dew Point Temperature (DP): The temperature at which air becomes saturated with water vapor and dew begins to form.

To switch between Dew Point (DP) and Wet Bulb (WB) temperature displays, press the DP/WB button.

Note: For stable and accurate readings, especially when moving the device between different environments, allow approximately 10 minutes for the sensor to adapt to the new conditions before taking measurements.

Unit Switching (°C/°F):

To switch the temperature unit between Celsius (°C) and Fahrenheit (°F), short-press the °C/°F button.

MAX/MIN Value Display:

To view the maximum or minimum recorded values since the device was powered on or reset:

Press the MIN/MAX button once to display the maximum (MAX) values.
Press the MIN/MAX button again to display the minimum (MIN) values.
Press the MIN/MAX button a third time to return to live readings.

Data Logging (MEM/READ):

The YT606 can store up to 99 groups of data.

To store the current reading, press the MEM button.
To recall stored data, press the READ button. Use the up/down arrow buttons to navigate through the stored data groups.

Maintenance

Cleaning: Use a soft, dry cloth to clean the device. Do not use abrasive cleaners or solvents.
Storage: When not in use for extended periods, store the device in a cool, dry place. Remove batteries to prevent leakage.
Sensor Care: The high-precision sensor is delicate. Avoid touching it directly or exposing it to dust and debris.

Troubleshooting

Problem	Possible Cause	Solution
Device does not power on.	Dead or incorrectly installed batteries.	Check battery polarity or replace with new AAA batteries.
Inaccurate readings.	Sensor not acclimated to environment; sensor dirty or damaged.	Allow 10 minutes for acclimation. Gently clean sensor area with a soft brush or contact customer support if damage is suspected.
Display is dim or flickering.	Low battery.	Replace batteries.
Auto-shutdown occurs too quickly.	Automatic power-off function is active.	Refer to the full user manual to disable the auto-shutdown feature if continuous operation is needed.
