2. UNPACKING
The instrument should be carefully inspected for signs of damage that may have occurred
in transit. In the unlikely case that damage has been sustained, DO NOT use the
instrument, but please retain all packaging for our inspection and contact your supplier
immediately.
3. PRODUCT IDENTIFICATION LABEL
The unit delivered should be carefully inspected to ensure it is suitable for the application
required. Detailed information on the product is included in the identification label and the
user manual.
Please ensure, that the temperature range of the IWTxT is suitable for the intended
application and that the IWTxT unit will not be subjected to temperatures and/or
temperatures greater than those specified in this manual.
4. INSTALLING/CHANGING THE BATTERY
A Lithium 3.6 V battery is included inside the IWTT transmitter. The battery may be changed at
any time, but the correct polarity must be observed at all times! After the battery has been
changed, the unit should be switched on using the SW3 push button and then SW1 should be
pushed for 5s. This is to ensure the battery life count is reset correctly when a new battery is
installed.
The internal LED will flash 5 times to indicate this procedure has been carried out successfully.
The battery life is determined by the rate the transmitter sends the Temperature value to the
receiver, this update rate can be selected using Dip Switch 1 and the default value is 10s.
A second set of batteries is used to provide the excitation supply to the external 4-20 mA
transmitter. Polarity should again be observed when installing this battery pack.
Please dispose of all batteries as specified by the legislator according to the Closed Substance
Cycle and Waste Management Act or country regulations.
