3.4.4.2 With the supplied cable
If you want to
extend the supplied cable
, measure the source
impedance including the supplied cable, as follows:
1. Connect the supplied power cable to the DC power source.
2. Connect the other end of the power cable to the Mini part of the
Mini/Micro T-connector.
3. Connect the cable for the SAILOR 3027 to the T-connector, but do not
connect the other end to the terminal.
4. At the unconnected end of the CAN cable, measure the source
impedance as described in the next steps.
5. Measure the voltage without load (R.var disconnected).
6. Set the current to e.g. 1 A by adjusting R.var.
7. Measure the corresponding voltage change.
8. Calculate the source impedance from the voltage and the current.
Example:
1 A and 950 mV. Source impedance: 950 mV/1 Amp = 950
mOhm.
You can use this source impedance to calculate the maximum length of the
extension cable.
