• Length measurement

- Measures the length of the bus line

- Determines the location of a short circuit between CAN_H and CAN_L

• Signal test

- Tests the transmission rate

- Tests the electrical signal level on the lines CAN_H and CAN_L

- Tests the signal edges on the lines CAN_H and CAN_L

Range

• Real-time mode

- Measures the bus load

- Measures error rate, failure rate and number of errors

Once a test has been completed, the results can be read directly from the
device’s display or can be uploaded to a PC using the software provided.

Safety

Disposal

The module must be disposed of properly when it reaches the end of its
service life.

3-2 Operating Manual: PSS SB TESTER

Operation

Supply

The PSS SB TESTER is supplied via a battery, which is located in the
back of the housing.
A charged PSS SB TESTER can be operated for 1 to 2 hours, depending
on the application conditions. If the battery charge drops to a particular
value during testing, the message “Charge battery” will be displayed and a
beep will sound. If the battery charge becomes so weak that the supply
can no longer be guaranteed, the PSS SB TESTER will switch off
automatically. The battery will need to be recharged. This takes approx. 1.5
hours.

INFORMATION

When the PSS SB TESTER is used for the first time or after storage
periods of more than 6 months, the battery will need to be charged for at
least 4 hours.

Charging the battery

• Plug the charger’s mains connector into a socket (110/230 VAC, 50 Hz).

• Take the PSS SB TESTER battery and plug it into the charger. The
charger is designed in such a way that the battery can only be inserted at
the correct polarity.

The start of the charging process is displayed via a red LED on the
charger’s connector (100 % on).
When the main charge is complete, the charger automatically switches to
“Conservation charging” mode and the LED flashes (25 % on, 75 % off).
If the main charge cannot be completed within 2 ½ hours, the charger
automatically switches to “Conservation charging” mode.
If the battery is extremely depleted, the LED will flash (50 % on, 50 % off)
when the battery is plugged into the charger. The battery is then charged
with a reduced charging current until the battery is regenerated and can be
switched to “normal” main charge mode.

Operating Manual: PSS SB TESTER 4-1

Operation

INFORMATION

The battery should not be left in the charger over a long period of time
(several weeks).

• Charge the battery until the LED on the charger flashes (25 % on, 75 %
off)

• Remove the battery and place in the PSS SB TESTER.

Commissioning

Switching on
