CAR PFS RCal Kit for CAR PFS-80

Calibration kit for CAR-PFS according to standard

• Low inductive, high precision lead resistors
• For power line and data line
• Software procedure for verification

According to: LV 124, LV 148, and VW 80000

The CAR-PFS-RCal Kit includes four load resistors for verification of pulses E10 and E13 of LV124 of the CAR-PFS80. There, power lines and data lines can get verified.

The two load resistances 1Ω and 100Ω can directly plugged into the device for verification of the power lines in LV124 and LV148.

The box with the 1Ω and 1kΩ resistance is for verification of data lines in LV 124.

Corresponding verification procedures are predefined in the setup menu of the Car-PFS80.

Power Lines:

This point applies to LV 124 (E10). The LV 124 requires reference measurements to prove the slew rate. For reference measurement, a 1Ω and a 100Ω (±5%) resistor (low inductance) are connected to the output.

The CAR-PFS-R-CAL Kit avoids, with its short connections, additional inductances. If you use another resistor, the reference resistor shall be connected as close to the “ +OUT” and “- OUT” sockets of the CAR-PFS as possible.

Please note the high power loss in the case of the 1 Ω resistor operated at 11 V according to the LV 124, the test setup should be prepared without power and carried out only with the predefined verification procedure! This procedure is located in the setup menu of the CAR-PFS80 generator.

Data Lines (2A):

This point applies to LV 124 (E13). The LV 124 requires reference measurements to prove the slew rate. For reference measurement, a 1Ω and a 1kΩ (±5%) resistor (low inductance) are connected to the output.

A short cable connection must be established! A positive effect is also a twisting of the supply line.

Please note the the high power loss in case of the 1 Ω resistor. The maximum current of 2A must not be exceeded! The test setup should be prepared without power.
