- Open RC-4 temperature data logger data management software, it will automatically upload the data log by default setting of software. It could cancel “Auto upload data” in the menu of “system setting”. 3. After data uploading, you could check data table, curve graph and report, and export them in format of Word/Excel/PDF/TXT.Click the icon “save data” to save the data to the computer data base; click the icon “send mail” to send the data to the set mailboxes. For the details, please see “system mail setting”
Note: RC-4 parameters setting is operated through computer, for the details, please see the help file of RC-4 temperature data logger data management software.
Function description:
The data logger display interfaces includes: status display, record capacity
display, time display, date display, Max. temperature display, Min.
temperature display, temperature upper limit display, temperature lower limit
display.
If no operation within 15 minutes, the data logger will turn off the display
automatically. If the display has been timed off, short press the button to
enter the display interface. Each time press the button, it will shift among
the display interfaces according to the sequence as described above. If the
internal buzzer is selected, you could set the button warning tone in RC-4
temperature data logger data management software.
The data logger display interfaces includes: status display, record capacity
display, time display, date display, Max. temperature display, Min.
temperature display, temperature upper limit display, temperature lower limit
display If no operation within 15 minutes, the data logger will turn off the
display automatically.
If the display has been timed off, short press the button to enter the display
interface. Each time press the button, it will shift among the display
interfaces according to the sequence as described above. If the internal
buzzer is selected, you could set the button warning tone in RC-4 temperature
data logger data management software.
Status display interface: See Figure 1
After short press the button, it enters to the status display interface from
the display turn-off status. The temperature displayed in the LCD screen is
the current environmental temperature. In the status display interface:
If the symbol lights, indicate the data logger is in the status of
recording.
If the symbol flashes, indicate the data logger is in the status of start
time delay.
If the symbol lights, indicate the data logger has stopped/terminated
recording.
If neither of the symbols ****and lights, indicate the data logger has not
started its function of recording.
If the symbols of and light, indicate the measured temperature exceeds its
temperature upper/lower limit.
The temperature shown in this status display interface is the current
environmental temperature.
Record capacity display interface:
When the symbol “Log” lights, it indicates that it enters to capacity
display interface. The number shown in the LCD is the recorded temperature
group, the interface is shown as Figure 2:
Time display interface:
In time display interface, it displays the hour and minute of the data
logger. The time format is 24 hours.
The display interface is as shown in Figure 3:
Date display interface:
In date display interface, it displays the month and date of the data
logger, display interface is shown as Figure 4:
Note: The data below the symbol “M” indicates month, and the data below
the symbol “D” indicates date.
Max. temperature display:
The maximum temperature valued measured since the beginning of recording,
its display interface is shown as Figure 5:
Min. temperature display:
The minimum temperature measured since the beginning of recording, display
interface is shown as Figure 6:
Temperature upper limit display interface shown as Figure 7:
Temperature lower limit display interface shown as Figure
8:
Operation Instruction:
- Start recording
After setting RC-4 parameters in data management software, the function of recording has not been started yet, at this time, press the button for more than four seconds in the status display interface, the symbol lights, and the recording has started. If the symbol flashes, indicate the data logger is in the status of start time delay.
-
After finishing parameters setting in RC-4 temperature data logger data management software, it will clear up the recorded historical data. Please read and save data before parameter setting! 2. Stop recording
1. The data logger will automatically stop recording when the recording capacity is full. In the status display interface, the symbol “ ” lights, it means recording stops.
2. If “permit stopping by pressing button” is set, press the button for more than four seconds, in the status display interface, the symbol “ ” lights, it means recording stops.
3. It could stop recording though setting in data management software. In the status display interface, the symbol “ ” lights, it means recording stops.
After the data logger stops recording, it could not be started again by press the button. It could only be started by setting the parameters in RC-3 data management software. 3. Alarm status Instruction
During recording, if the measured temperature is higher than temperature upper limit, in the status display interface, the symbol * lights, indicating upper limit alarm; if the measured temperature is lower than temperature upper limit, in the status display interface, the symbol “ “lights, indicating lower limit alarm.
If the internal buzzer is selected, you could set the alarm sound in RC-4 temperature data logger data management software, it has three modes: Disabled, three beeps , ten beeps.-
Record interval
The record interval could be set in RC-4 data management software. After setting, it will save the data in the data logger according to the set record interval. In RC-4 data management software, when record interval is set, click the setting bar of record time length, then the software will automatically calculate the record time length. -
Record time length
The “record time length” means that the total record time when the memory reaches its full capacity.
After the record interval is set, click at the setting bar record time length, then the software will automatically calculate the record interval. -
Clear the recorded data
The recorded data could be cleared through setting the parameters in RC-4 data management software. -
Inner clock and calendar
The clock could be adjusted by RC-4 data management software. -
Sensor failure
When there is a sensor failure or over temperature range, it could query by two methods as below;
-
- When the temperature exceeds temperature range or there is a break circuit or short circuit, it will display “Ert’ in the position of temperature in the status display interface.
- There will appear an instruction of “Sensor error” in RC-4 data management software.
- Battery level indication
The battery level could be displayed in RC-4 LCD screen.Battery level indication| Level
---|---
| 25% ~ 100%
| 10% ~ 25%
| <10%
Note: If the battery is in a very low level (<10%), please replace the battery timely.
