An exclamation mark in a triangle indicates important notes in these operating instructions that must be strictly observed. The “arrow” symbol alerts the user to the presence of important tips and notes on using the device. This device is CE compliant and fullls all applicable European guidelines.58

The battery-operated portable data logger DL-200T has an internal temperature sensor, DL-210TH has an internal temperature/humidity sensor and DL-220THP has an internal temperature/humidity/air pressure sensor. Measuring data is recorded automatically at adjustable sampling rates from 1 minute to 24 hours. At most 40,020 measuring values can be saved. Measured values can be immediate read on the LC display. The data logger can be congured online or by the included software. The product is connected to a computer like a regular USB memory stick and read out there. It automatically generates a graphical report in PDF format. A long-life lithium battery ensures a long recording time. With attached protective cap, the product is dust tight and jet water- protected and can be used indoors and outdoors. Do not use the device if the housing is not completely shut or if the protection cap is not attached properly. Measuring under adverse ambient conditions like dust and ammable gasses, vapours or solvents is not admissible. The safety instructions must be followed unconditionally!

9. INITIAL OPERATION

a) Protective cap The data logger is only dust tight and jet water protected with attached protective cap (12) and rubber seals (9, 10). This protection allows permanent logging operation in damp rooms and outdoors.

• Only remove the protective cap for replacing the battery or reading the data on the computer.

• Remove the protective cap by pulling it off from the data logger. The protective cap ts tightly due to the rubber seal (10).

• Place the protective cap tightly back onto the data logger. b) Connect to the computer

• Remove the protective cap (12) from the data logger.

• Connect the data logger to an available USB port of your computer.

• The computer recognizes the new hardware. The model type of your data logger appears as a mass storage device on your computer. c) Disconnect from the computer

• Eject the data logger from your computer and remove it.

• Place the protective cap back on the data logger. d) Choose start/stop mode

• Choose start mode from “RECORD START CONDITION” during conguration.

• Choose stop mode from “STOP STYLE” during conguration.68 e) Dene date and time during conguration

• Select month, year and time with date picker and time sliders. The time will be shown as “TIME” in HH:MM:SS format. Conrm with “DONE”. Date and time settings are displayed in the corresponding elds.

• Alternatively, click “NOW”, if you require an immediate start of logging. Actual date and time - as per locally set on your computer - will be lled automatically into eld “START TIME”/“STOP TIME”. f) Button ENTER

• Press button ENTER to switch between maximum and minimum reading.

• Press and hold button ENTER for few seconds to start/stop logging or activate/deactivate pause function.

• Install the battery before rst-time use or replace the battery when the battery symbol “ “ appears in the LC display. Removing and replacing batteries does not delete data or settings.

• Remove the protective cap from the data logger.

• Press and hold the button RELEASE BATTERY COMPARTMENT (7) and pull out the logger unit from the housing. The housing ts tightly due to the second rubber seal (9).

• Release the button RELEASE BATTERY COMPARTMENT.69

• The battery compartment (4) is on the back of the logger unit. Insert a new and suitable battery (see “21. Technical data” on page 94) into the battery compartment observing correct polarity (positive/+ and negative/-).

• Slide the logger unit back into the housing. Ensure that the LC display matches to the LCD window of the housing.

• Place the protective cap back onto the data logger. The data logger performs best at room temperature. If the item is used at extremely low temperatures, the battery life is reduced. In such case, you can reduce power consumption of the data logger in order to prolong the operation time as following - disable LC display - disable LED alarm - set a longer sampling rate For details refer to chapter “11. Conguration” on page 69.

After inserting a battery, congure the data logger either by software or by website. Select logging parameters like sampling rate, start time, recording time, pause function, LED ash interval, enable/disable LC display and PDF report settings. Conguration terminologies and commands may differ between software and website. The following instructions and explanations are based on the terminologies and commands found on the conguration website. After creating the conguration le, copy it to the data logger!70 a) Install software
