Constantan wire of the probe. This extra junction will cause a large error in the temperature
readings.
Most Thermocouple probes are of the “grounded junction” type. This means that the “hot
junction” is also connected to the probe’s body. As this body is connected for example to the
exhaust manifold, the sensor wires are essentially grounded through that. The same is true if a
home-made thermocouple junction is used as described above by twisting the wires and if that
wire-twist is connected to some grounded engine part.
You can check if you have a grounded junction type by measuring between the probe body and
one of the Thermocouple wires. If you have continuity, you have a grounded junction.
The DL-32 NEEDs a grounded junction.
If you don’t have a grounded junction, connect a wire between the TK- input of the DL-32
and the ground terminal of the DL-32.
4. Recording with the DL-32
4.1 Time and Date
The DL-32 has an internal real-time clock device that will continue to run even when power is off.
This clock device DOES NOT automatically set the correct time and date during changes from
daylight savings time and back.
To set the real-time clock device the DL-32 must be connected to a computer as if it were
prepared to be programmed (see chapter 13). When the LM Programmer software connects to
the DL-32 it will automatically synchronize the DL-32’s clock to the current time and date setting
of the computer.
Therefore it is very important that your computer’s time and date is set correctly.
4.2 SD Cards
The DL-32 accepts standard secure digital (SD) cards with a capacity of up to 2 Gbyte. The cards
have to be formatted in the FAT16 file system, as most SD cards are. SD cards are graded in
speed grades like 1x, 2x, 4x and so on. The minimum speed required for an acceptable SD card
is 4x.
The DL-32 ships with a 128 Mbyte SD card.
To be able to record to an SD card, the Write Lock Slider on the left side of the SD card must be
in the Unlocked position.
