Reset Switch
In the unlikely event of the logger locking up, press
the Reset button briefly.
After pressing Reset, four LED flashes indicate that the DL6 is
performing a warm reset. Program and data are preserved
and logging will resume.
Holding Reset for more than 5 seconds will initiate a cold
reset, with the status LED flashing an additional four times. A
cold reset restores the factory-set default program and deletes
all data.
Status LED
Tap the logger - the LED should flash as follows:
If it does not flash, check the battery.
Analogue Channel Considerations
The differential analogue channels accept signals
of nominally 0 to 1V, with a full signal range of –0.01 to +1.15 V. Each channel has
V+ and 0V connections to allow the switched powering of sensors. Sensors can be
powered up with an adjustable warm-up time prior to taking sensor readings. Warm-
up times of multiples of 1 second are permitted. The supply voltage is unregulated.
Ensure analogue signals are kept within the permitted input voltage range (-0.2 to +3 V
relative to logger ground
then the input signal may need a 10K resistor between IN- and ground.

To operate the DeltaLINK software for the DL6 logger you need:
A PC running Windows XP, Vista, 7,8,10 or a later version.
Microsoft Excel 97 or later for the Dataset Import Wizard.
One free RS232 serial port or USB-RS232 adapter.
DVD or internet connection for installing DeltaLINK.
A minimum of 50MB of available hard disk space.
DL6 to PC RS232 cable (supplied with DL6).
