Instruction Manual

1. Features

The AT210 wireless digital thermometer can be used for remote temperature

monitoring. It consists of two units: AT210-A (slave unit) and AT210-B (master unit).

The slave unit connects to the temperature sensor and displays measured value. It

also sends the measured temperature reading to the master unit and allow remote

monitoring and remote parameter setting through wireless connections. The master

unit can communicate with up to 10 slave units. The AT210 thermometer have two

alarm settings for a built-in buzzer. One can be used for high limit alarm and the other

can be used for low fuel (limit) alarm. This thermometer can also store the highest

temperature reading with a time stamp during the temperature monitoring process. The

slave unit has a 12VDC 2.5mm power output that is synchronized with the build-in

alarm buzzer, which can be used to drive an external buzzer or other devices. Both

units are powered by 12VDC through an 2.1mm AC adapter for continuous operation. It

can also be powered by a car battery directly.

2. Alarm indicator: blinking when alarm is triggered.

3. Peak value indicator: stay solid on when peak value is displayed; blinking when the

time stamp of the peak value is displayed.

4. Set key: enter code; confirm input value.

5. Shift key: shift digit; mute the alarm buzzer.

6. Down key: change digit value; move to the previous parameter; display peak

temperature and the time when peak temperature is reached/ reset peak values.

7. Up key: change digit value / move to next parameter / change brightness.

4. Connectors on the meter

The connectors on the meter are shown in Figure 2. Connecting the 12V DC power

adapter to the connector 1 from wall outlet. Connecting the external buzzer to

connector 2. The polarity for this socket is center pin positive (+), outer collar negative

(−). Connect the K thermocouple to terminal 3. Please note that thermocouple

connector also has polarity. The wide blade should go to the wide slot.

5. Key functions during temperature monitoring

During the normal temperature monitoring mode, you can mute the alarm, check the

peak value, and change display brightness with the keys on the front panel (Figure 3).

1. Temporarily

mute the alarm

Key Function Descriptions:

1. Temporarily mute the alarm. When the temperature reaches the alarm

temperature, the alarm indicator will flash and meter will start beeping. Press Shift key

once can temporarily mute the alarm. Alarm will be triggered again if the alarm set

temperature is reached again. Please see Section 6 for detailed explanation alarm

settings.

2. Check the peak value. Press Down key once to show peak temperature, and the

MAX LED will light up; press Down key again to show the time stamp, i.e., the time

when peak temperature is reached (count from the start of the timer, unit is seconds),

and the MAX LED will flash. If the temperature continues rising, a new peak

temperature and its time will be written to the memory to replace the previous peak

value. Please see Section 9 for details.

3. Dimmer the display brightness. Press Up key to toggle the display brightness

between the dimmed display and the normal bright display. The brightness of the

dimmed display is determined by the parameter "brit" described in the later section of

the manual (see Section 7).

6. Alarm setting (code 0001)

The meter has two programmable alarms that can be set to turn on the buzzer at

specified temperatures. The alarm1 is controlled by parameters AH1 and AL1; the

alarm2 is controlled by AH2 and AL2. These parameters can be accessed by code 0001

(see Table 1).
