Ports
2.2 Battery
compartment
The CANcheck is powered by 4 x 1.5 V batteries or 4 x 1.2 V rechargeable batter-
ies Mignon (AA). The battery compartment is on the back of the device. To re-
place the batteries you require a slotted screwdriver (blade width approx. 5 mm).
Please use it to press the plastic spring of the catch together and carefully lift off
the cover.
Please note:
•
The rechargeable batteries cannot be recharged via the USB connector.
Please remove the rechargeable batteries from the battery compartment and
recharge them in a commercial battery charger.
•
For rechargeable batteries, the capacity given by "Settings/Battery voltage" is
not valid. It is only valid for batteries.
•
For rechargeable batteries, please check the voltage given by "Set-
tings/Battery voltage". You should recharge the rechargeable batteries when
the voltage drops below 4.8 V.
2.3 Trigger
output
When a configurable 11-bit or 29-bit-identifier is received, the CANcheck gener-
ates a signal pulse on the trigger output. The signal pulse has the following prop-
erties:
•
positive and negative signal pulse at the end of the telegram
•
10 V peak-peak without load
To use the trigger output, connect the CAN/trigger cable (see section 10.2) to the
CANcheck. The "SUB-D9 connector with CAN cable and BNC cable" belongs to the
CANcheck. The "SUB-D9 connector with CAN cable" belongs to the CAN network.
Usually, an oscilloscope is triggered by the trigger output. The telegram of the
configured 11-bit or 29-bit identifier is then displayed on the oscilloscope. In this
way the level measurements of the CANcheck can be supplemented with meas-
urements with the oscilloscope.
