DTM-320/DTM-321/ DTM-322 is a handheld instrument with temperature and humidity measurement functions. DTM-321 / DTM-322 tool

Temperature Coefficient:

The following inaccuracies need to be added:

Notice:

When the operating temperature is not within the range of 18°C~28°C, each

until the memory is exhausted.

Each time you press the "REC" button to start recording, until you press "REC" again to end the recording, it is called a set of data. You can record unlimited sets of data until

Reading x 0.01% ± 0.06 °F

Identify the total error.

Reading x 0.01% ± 0.03 °C

The above accuracy is the specification of the instrument itself, but in actual application, the specification error of the thermocouple temperature rod itself needs to be considered. Please refer to the relevant specification sheet to confirm

4.3 Connect the temperature thermocouple: ( DTM-321/DTM-322 model )

Instructions for use

4.7 Timer function: ( DTM-320 model )

4.8 Relative reading function (return to zero): ( DTM-320 model )

4.2 Method of expressing remaining memory space: (DTM-322 model )

4.9 Memory function: ( DTM-322 model )

4.6 Time function: ( DTM-322 model )

4.5 Lock the reading value:

Press the "HOLD" button to lock the displayed reading value, and press it again to unlock the reading value; when the reading value is locked, the ÿREL, MAX/MIN and "°C/°F" functions

will not be executed.

After powering on, a number will appear below the LCD, which represents the remaining recordable size of the instrument's

memory. As shown in the picture on the right: it represents the remaining 16,000 pieces of data available for use in the memory.

When the "REL" key is pressed , the temperature and humidity meter will record the current reading and display the difference between the current reading and the memory reading. Press

again to deactivate this function.

Press the " TIME " key to switch to display time, which will display the year, month, day and time. Press any key to leave the time display mode and restore the reading value display mode.

Note: If the time is

2000/01/01 00:00 every time it is turned on, it means that the clock battery needs to be replaced. Remove the bottom cover and replace the 3V button battery.

Insert the connector plug of the thermocouple temperature measuring rod into the connector at the top of the thermometer and hygrometer. Please pay attention to the positive and negative polarity of the connector.

4.1 Power on and off: Press

the I key to power on or off the thermometer and hygrometer.

4.4 Temperature unit selection: Press

the "°C/°F" key to select the temperature unit displayed in °C or °F.

Press the "REC" button to start recording according to the set recording time interval. After starting recording, the "REC" symbol

will appear in the upper right corner of the LCD. Pressing the "REC" key again will stop recording, thus completing a set of data.

When the memory is full, the "REC" symbol will flash once a

second. To view the memory contents, you need to use the included RS232 cable and software to transfer the memory contents

to the computer. If the memory is full and you want to record again, you must clear the memory first. To clear

the memory, first

turn off the phone, then press and hold "REC", then press and hold the power button for two seconds, and then release all keys. ,

at this time "CLR" will appear on the LCD (as shown on the right), indicating that the memory is being cleared. After the clearing is

completed, "CLR" will disappear, and the "REC" symbol will stop flashing and disappear.

Press the "TIMER" button to start the timing function, which is displayed as minutes: seconds (m:s). Press it again to stop the timing action; press it again to continue the timing action, so

that the entire timing program can be repeated. When the timer exceeds 59 minutes and

59 seconds, the display unit will change to hours: minutes (h:m). When the "TIMER" button is pressed for 2

seconds, the timer will be reset.

"CLR" appears, indicating that the memory is

being cleared.

Step 2: Press the "HOLD" (INTV) key to start entering the time interval setting (Figure 2)

4.14 Low battery indication:

(figure 1)

When it appears on the display, it means the battery is low and needs to be replaced with a new one.

(figure 2)

4.13 Automatic shutdown:

When turned on in the normal way, a symbol will appear on the upper left side of the LCD, indicating that it will automatically shut down if there is no key operation or RS232

connection and no data is recorded within 30 minutes. When you want to release the

automatic shutdown mode, you can press the "HOLD" button and then turn on the phone. The symbol on the LCD will not be displayed, indicating that the automatic shutdown has been released.

When RS-232 and REC are activated, the watch will automatically release the automatic shutdown function. .

4.11 Recording time interval setting: ( DTM-322 model )

Step 2: Press the "CLOCK" button ("TIME") to enter the time setting mode (Figure 2)

(figure 2)

4.12 Maximum and minimum reading function:

Step 3: Press "REC" ÿ or "°C/°F" ÿ to increase or decrease the number. If you want to quickly increase or

decrease the number, please hold this button and press "Time" to change the adjustment

items. The order is: year ÿ month ÿ Day ÿ Hour ÿ Minute ÿ Second, then press "TIME" to save

the setting value. During the setting process, if you want to leave the setting mode without saving

the setting value, you can press the power button to end it.

Step 3: Press "REC" ÿ or "°C/°F" ÿ to increase or decrease the number. To quickly increase or decrease the

number, please press and hold this button, and then press the "HOLD" (INTV) button to adjust

the next item, and finally press "HOLD" (INTV) to save the setting value. During the setting,

if you want to leave the setting mode without saving the setting value, you can press the power

button to end. [Note] The setting mode is divided

into :Second

(figure 1)

When the "MAX MIN" key is pressed, the temperature and humidity meter will record the maximum value and the

minimum value at the same time; when MAX appears, the displayed value is

the recorded maximum value. Press the "MAX MIN" key again , and the value displayed when MIN appears is the minimum

recorded value. Press the "MAX MIN" key again . When MAX MIN flashes at the same time, the value displayed is the current measurement value.

Press the "MAX MIN" key again to return to the MAX display. In this way, the user

can select the appropriate reading value display, and the reading value during the period will be updated at any time.

This operating state will end when the "MAX MIN" key is pressed for 2 seconds.

Step 1: Press and hold the "MAX MIN" button and then turn on the phone to enter the setting mode. (Picture 1)
