AT4202/4204/4208 Portable multi-channel temperature Tester

operating environment

The AT4202/4204/4208 needs to be used under the following environmental conditions:

Temperature: 0℃～55℃,

Humidity: Less than 70%RH at 23°C

Altitude: 0~2000 meters

to clean

Do not clean the inside of the appliance.

Note: Do not use solvents (alcohol or gasoline, etc.) to clean the container.

Please use a clean cloth dampened with a little water to clean the case and panel.

Replacement battery

The instrument has a built-in rechargeable lithium battery, which has been installed in the battery compartment of the instrument at the factory. If replacing the battery, follow the steps below

carry out

Figure 1-1 Replacing the battery

1. Use a screwdriver to loosen the screws on the battery cover and remove the battery cover.

2. Take off the pinch head on the old battery, and pinch the pinch head on the new battery, pay attention to the direction of the pinch head.

3. Put the new battery into the battery compartment, cover the battery cover, and tighten the screws

Adjust the support

The appliance support has 2 positions for user convenience: 60 degrees and 45 degrees.

Using the 45-degree position can make the crutch more stable.

use external power

The standard power adapter ATL909 is equipped with the device.

In addition to powering the device, the power supply also charges the lithium battery inside the device, so the power adapter cannot be replaced. It is recommended to use the power adapter.

The company uses the power supply L909.

start up

The button is a light touch button, press the power switch button, the device will be turned on or off.

Connection to test side

AT4202 has 2 sets of input ports.

AT4204 has 4 groups of input ports.

AT4208 has 8 groups of input ports

<Measurement display> page 

No matter what page you are on, you only need to press the [Meas] shortcut key to enter the <Measurement Display> page. The <Measurement Display> page mainly highlights the measurement results. At the same time, change the font color symbol display for the current selection result. One common function can be set on this page, which includes:  Channel setting Note: The measurement data and selected results are only available on the <Measurement Display> page

5.1 <Setting Display> page At any time, you only need to press the [Setup] shortcut key to enter the <Setting Display> page. <Setting Display> page can complete all the settings related to measurement, but the monitor does not display the measurement results and selected results, and the monitor is in a waiting state. These settings include the following parameters:

 Model – sensor model setting

 Unit – temperature unit setting

 Rate – Sampling speed setting

 Beep – Buzzer setting

 High Limit – Comparator high limit setting

 Lower limit – comparator lower limit setting

 Storage settings – storage method settings

Time  Interval  – digital recording interval setting

Notice:

1 The steps to record data are: first select [USB DISK] or [MICRO SD], then insert the MICRO SD card or

USB memory, the device automatically starts recording data.

2 This time interval indicates how often to record the scan results, because scanning all channels requires the least

The time is 5S, so it is recommended to set the interval time not less than 5S.

The data consists of two parts, the recording time and the corresponding channel temperature.

example:

The current time of the device is: 2013-11-20 15:

Create folder name: 20131120, file name: 153035.CSV under the root directory of the storage

The data format is float type, retaining one decimal point, and the channel is marked with ","

<System Configuration> page

At any time, you only need to press the [SYST] key to switch to the [System Configuration] page

The <System Configuration> page includes the following settings:

 date

 Time

 language

 Documentation

 Touch screen

 Brightness adjustment

 Reduce brightness

 Automatic shutdown

All the settings on the system configuration page will be automatically saved in the system, and will be automatically loaded at the next startup.
