TEMPERATURE DATA LOGGER (DL2B)
USER MANUAL
Features
Data logger simultaneously displays minimum, maximum and current
temperatures
The unit will provide a visual and audio alert when temperature rises above or falls
below the high and low set points.
The min/max feature is designed to monitor and store the highest and lowest
readings until the memory is cleared, or removal of battery.
The temperature sensor is enclosed in a glycol-filled bottle, protecting it from rapid
temperature changes when refrigerator/freezer door is opened.
Low battery alert function ( battery symbol flashes) User can select oC or oF temperature display Measuring temperature range -45 ~ 120 oC ( or -49 ~ 248 oF) Operating conditions: -10 ~ 60 oC ( or -50 ~ 140 oF) and 20% to 90%
non-condensing (relative humidity) Accuracy : ± 0.5 oC (-10 ~ 10 oC or 14 ~ 50 oF), in other range ± 1 oC ( or ± 2 oF)

To Use
NOTE: Before use, remove and discard the clear plastic protective film from
the screen (LCD). Place the temperature sensor (in glycol bottle) in the
location to be monitored, such as inside a refrigerator or
freezer. The data logger may be placed on top of unit with LCD display easily
visible and the alarm audible. Data Logger displays internal temperature of
unit being monitored, as well as maximum and minimum temperatures reached. The
Data Logger’s maximum and minimum readings reflect the highest and lowest
temperatures since the unit was powered or since the MIN/MAX history was
cleared. If the temperature measurement rises above or falls below the set
temperature range, the alarm will sound. To silence the alarm, press any key
ONCE. Clear MIN/MAX history once the unit is stable.

High Alarm Temperature Setting
From the main display screen: Hold the SET key for 3 seconds. Use the up and down arrows to adjust the password to the correct password. By default the correct password is 50. Press SET key ONCE to confirm the settings. By default, the high and low alarm settings are 8 oC and 2 oC respectively. To reset high alarm and low alarm temperature settings, follow instructions below. From the main display screen: Hold the SET key for 3 seconds. Enter the correct password then press the SET key ONCE to enter the HI Temp Alarm setting mode. Use the up and down arrows to adjust the temperature accordingly. Press SET key ONCE to confirm the settings.

Low Alarm Temperature Setting
Alarm Hysteresis
From the main display screen: Hold the SET key for 3 seconds. Enter the
correct password then press the SET key 2x to enter the LO Temp Alarm setting
mode. Use the up and down arrows to adjust the temperature accordingly. Press
SET key ONCE to confirm the settings.
Hysteresis is the tolerance band to prevent alarm chattering. For instance, if
the high alarm temperature is set at 8 oC with a hysteresis of 1 oC, once the
alarm is activated, it will not return to normal until the temperature goes
below 7 oC. By default, the alarm hysteresis is set at 1 oC. To reset, follow
instructions below.
When the temperature is higher than (Low Alarm Temperature setting + Alarm Hysteresis) it will exit low temperature alarm.
When the temperature is lower than (High Alarm Temperature setting Alarm Hysteresis), it will exit high temperature alarm.
When an alarm condition occurs, HI-ALARM and LO-ALARM icons will appear on the
display along with a beeping sound to alert user. The beeping sound will stay
ON until the unit gets back in range. Press any key ONCE to stop the beeping
sound. The high and low indicators will remain on display even when the unit
gets back in range. Press for 3 seconds to clear the HI and LO alarm icons.
Note- The HI and LO alarm icons will only clear when the unit is back in range.
5 Alarm Delay
Start Delay Temperature Unit
From the main display screen: Hold the SET key for 3 seconds. Enter the correct password then press the SET key 3x to enter the Alarm Hysteresis setting mode. Use the up and down arrows to adjust the temperature accordingly. Press SET key ONCE to confirm the settings. The alarm delay is used to avoid unnecessary alarms when the temperature exceeds the set high and low alarm limits. This feature will delay alarm activation by the amount of time entered. By default, the alarm delay is set at 0 minutes. To reset, follow instructions below. From the main display screen: Hold the SET key for 3 seconds. Enter the correct password then press the SET key 4x to enter the Alarm Delay setting mode. Use the up and down arrows to adjust the time accordingly. Press SET key ONCE to confirm the settings. From the main display screen: Hold the SET key for 3 seconds. Enter the correct password then press the SET key 5x to enter the Start Delay setting mode. Use the up and down arrows to adjust the time accordingly. Press SET key ONCE to confirm the settings. From the main display screen: Hold the SET key for 3 seconds. Enter the correct password then press the SET key 6x to enter the Temperature unit setting mode. Use the up and down arrows to adjust the temperature units accordingly. Press SET key ONCE to confirm the settings.

Offset temperature
Logging/Record Interval
The offset temperature feature is useful for customers who require a positive or negative temperature offset to be applied to the temperature sensor reading. By default, the offset temperature is preset to 0 oC. To change the setting, follow instructions below: From the main display screen: Hold the SET key for 3 seconds. Enter the correct password then press the SET key 7x to enter the Offset temperature setting mode. Use the up and down arrows to adjust the temperature accordingly. Press SET key ONCE to confirm the settings. This setting tells the logger how frequently to take and store readings. The unit has a logging interval of 10 s to 240 minutes. By default, the logging interval is preset to 5 minutes. To change the setting, follow instructions below: From the main display screen: Hold the SET key for 3 seconds. Enter the correct password then press the SET key 8x to enter the Record Interval setting mode. Use the up and down arrows to adjust the time accordingly. Press SET key ONCE to confirm the settings.
Date and Time Setting
Press MIN/MAX and SET keys simultaneously and hold for 3 seconds to enter the date and time setting mode. Use the up and down arrows to adjust the year accordingly. Press SET to confirm and move to the month setting mode. Repeat the same steps to set MONTH/DAY/HOUR /MINUTE & SECOND

Using USB 3.0 Extension Cable
First step: Insert the USB Flash Drive. USB will display on the screen when
the logger detects the flash drive. Second step: Press DL button for 3 seconds
to download the data. CPL will display on the screen when the data is
successfully transferred to the flash drive. Third Step: When CPL displays on
the screen, the flash drive can be removed. Always clear the MEM/Data
logger’s internal memory before taking new readings. Otherwise, it will take a
long time to transfer large sets of data. Connect the male end of the cable
to the USB port then connect the flash drive to the female end of the cable.

Please note:
When the MEM is full, the unit overwrites old data If the temperature sensor
is loose or not inserted, “NP” will be displayed and the NP alarm will
be activated. When PAS is 0 there is no password. User can enter parameter
setup directly. When the logging interval (LI) =0, the record interval is 10
seconds. To modify the factory settings: Press the SET key for 3 seconds to
enter parameter setup state.
After adjusting parameters, press SET key button again for 3 seconds. “COP”
will be displayed. The modified and stored set temperature and parameters will
be new default settings. To resume original factory settings, press DL and SET
keys simultaneously for 3 seconds, “888” will display when the parameters are
reset to factory settings. To resume customers default settings, press and
keys simultaneously for 3 seconds, “888” will display when the parameters are
reset to customers default settings.
