• The default language is English. User may change it to one of six available languages. There are English, German, French, Italian, Spanish and Portuguese
• User programmable parameters are as follows:

Sampling rate
Select the sampling interval you need from 30 seconds to 2 hours.
Start delay
Select the start delay from 0 min to 24 hours. For example: If the delay is 5 minutes, and the sampling rate is 10 minutes, the real time to log the first measurement is 5 minutes after the START button is pressed. All measures after the first measurement will be at a 10 minute (or selected) interval.

Unit of Measurement
Select the unit that will be displayed on the PDF report and LCD. The selections are Metric or Imperial. In Metric, it is Celsius for temperature. In Imperial, it is Fahrenheit for temperature.
Password
The Password function is default OFF. The user may enable it to prevent unauthorized reprogramming prior pressing the START button. A Password may have up to 16 alpha or numeric characters.
Company Name
A user defined name, location or descriptor, all can be input as Company Name. It will be displayed on the PDF report as title, with a maximum of 20 characters.
Alarm types
While in logging mode, regardless of the Alarm Type, if the alarm is triggered, it won’t stop even the reading return to normal range or logging is stopped. The way to stop red alarm LED is to plug logger into computer to generate report or power off the logger.
Single: an alarm is triggered immediately when the measured value exceeds the alarm threshold.
Cumulative: an alarm is not triggered when the measured value exceeds the alarm threshold, but only once the overall average value during alarm delay duration exceeds the alarm threshold.
Disable: No alarm function during the logging process
Alarm delay
The preset alarm delay interval for a single alarm type is always ZERO. The adjustable alarm delay interval for a cumulative alarm type can be 5 minutes to 2 hours

Alarm Limits
Select the alarm threshold values. For example: if 2 – 8 deg C is selected, it means that an alarm warning will occur below 2 deg C, or above 8 deg C. The programmable alarm limit of each parameter is limited to one decimal. To summarize, to activate a alarm when 30 min average value of hazardous alarm delay period is higher than 8℃or lower than 2℃, please program the alarm delay as 30 mins, alarm type as cumulative and range as 2~8℃
NOTE: Above are valid both “monitoring” and “logging” mode.

Time zone
Before programming the logger the user must assure that the PC is set for the correct time zone. The logger will auto synchronize to the time zone of the PC, when “Save” is pressed. Time zone changes over the transit distance are not adjusted in the logged data.

The default value of above parameters are:.

Sampling rate: 5 min
Start delay: 0 min
Temp. Unit: °C

All measures after the first measurement will be ata 10 minute (or selected) interval

Alarm types
While in logging mode, if the alarm s triggered, it won’t stop even the reading return to normal range or logging is stopped. To stop alarm, must generate report or power off the logger. Single: an alarm is triggered immediately when the measured value exceeds the alarm threshold. Cumulative: an alarm is not triggered when the measured value exceeds the alarm threshold, but only once the overall average value during alarm delay duration exceeds the alarm threshold. Disable: No alarm function during the logging process.

Alarm delay
This is for Cumulative alarm type only. The adjustable alarm delay interval for a cumulative alarm type can be 5 minutes to 2 hours

Buzzer ON/OFF
The buzzer is default as ON. However, for power saving issue or this meter will be used in a place where noise is not accepted, user may turn off the alarm buzzer. This setting is only available b through meter keypad.

Alarmt threshold
Select the alarm threshold values. For example: if2-8°Cis selected as temp. control range itmeans that an alarm should occur below 2°C orabove 8°C. So, setup the high temp. alarm value as 8and low temp. alarm value as 2. H The programmable alarm limit of each parameter is limited to one decimal. The value of low threshold can’t exceed the setting of high threshold. High/Low threshold of temperature and humidity are both programmable

NOTE:

Above alarm threshold setting are valid both for “monitoring” and “logging” mode. The difference of these two mode is listed in page 5. This meter allows user great flexibility to monitor temperature and humidity with alarm feature regardless the meter is recording data or not.

3. Move the meter probe to the 75% salt bottle and press “SET” longer time to enter 75% calibration.
4. 75.3%” will flash on the monitor.
5. 60 minutes after, the flashing stops means the whole calibration has been completed and the calibration data have been saved in memory.
6. After step5, press “SET” longer time to return to normal display .

NOTE:
a) You can exit calibration without saving by pressing “START/STOP” +”SET” key for more than 5 seconds before step 5.
b) To get high accuracy, strongly suggest you to do the calibration at 23+2 C Temperature environment.

TROUBLESHOOTING

1. Power on but no display or meter doesn’t work .
   a) Make sure the time of pressing “START/STOP” key is more than 100 mSto turn on LCD display. b) Check the batteries are in place, good contact and correct polarity.
   c) Replace new batteries and try again. d)Move the batteries for one minute and put them back again

2. Calibration failure.
   a) Make sure the calibration bottle is under good sealing status when the meter’s probe is plugged into the salt bottle.
   c) Make sure the free air temperature is within 23+2 C when calibration is processed.

3. Error Codes
   a)E02: The value is underflow. Putitin room temp. to recover
   b)E03: The value is overflow. Put itin room temp. to recover
   c)E04: Caused by E02 or EO3 of temp. Solve E02/E03 first
   d)E11: RH calibration error. Need to re-calibrate.
   E)E32: IC read/write error. Need to return the meter to dealer for repair.
   f)E33: Circuit error in measurement portion. Need to return the meter to dealer for repair.

4. Why alarm LED is flashing but recorded data is OK?
   Alarm detection works every 10 seconds but data logging are possibly programmed as every 2 hours. In this condition, if alarm happens between two logging points, it might lead the recorded data is OK but alarm LED is flashing, especially if the alarm mode is set as “Single”. To program the alarm function as cumulative can reduce this situation

5. Why my datalogger could not record second time?
   After you download the data, please go back to configure page to re-check all the setting and then press “SAVE” to confirm. Then, once you long press the start key again to record, you will see green LED blink to indicate the recording is started and the new record will overwrite the kept old data in the logger memory IC.
