LKM DTM 3000 Operating Instructions

DTM 3000 DIGITAL THERMOMETER FOR THERMOCOUPLE SENSORS OPERATING INSTRUCTIONS
The Series 3000 digital thermometer, controlled by a microcontroller, stands out in terms of high accuracy, low power consumption, simplicity
of operation, and low weight.
The unit provides rapid high-precision measurements over a wide temperature range. Many parameters can be individually
adjusted via the serial interface. A large choice of sensors allows its application to a very wide variety of measurement tasks.

DESCRIPTION OF THE UNIT

Figure 1
Symbols in the LCD display
The unit is switched on by actuating the on/off button. First of all a segment check is carried out for approx. 2 secs. Here the display must look
like Figure 1. If segments are missing or the display appears to be very weak the battery should firstly be checked. If this is OK, the unit should
be sent to the manufacturer for inspection. During this period of time a self-test is carried out in the unit. If a defective function is detected, an
error number appears in the display. If the test has been completed successfully, the current measured value is displayed. The following error
messages can occur:
Err1 upper limit of measurement range exceeded
Err2 lower limit of measurement range not reached
Err4 battery flat
