If the leads are not connected, the digital measurement display indicates 0.00 and - - - - km. AC / DC current (C.A 6531) Current measurement corresponds to the 400 mA position of the switch. -
Page 11: Automatic Shutdown
< 6.7 V): the digital display indicates BAT and then, after 5 seconds, the shutdown buzzer sounds and the automatic shutdown function is activated. The instrument shuts down. 4.3.2 Fuse (C.A 6531) The fuse is automatically tested when switching on the instrument and at the end of each current measurement. -

This key can be used at any time except in voltage mode on the MΩ Ω Ω Ω Ω positions. Programming the capacitance per unit length (C.A 6531) When the switch is set to nF, a long press on the key activates the programming mode for the capacitance per unit length of the line to be measured. -
Page 14: Use
During programming, if you change the switch position, you lose what you have just done. You can quit the programming mode and record the value by another long press on the key. 5. USE To display the device software version and series number press the yellow button whilst switching on via the rotating switch. -
Page 15: Resistance Measurement
Resistance measurement Start up the instrument by setting the switch to 40 kΩ (C.A 6531) or 400 kΩ (C.A 6533). Connect the + and - leads to the measurement points. Note the resistance value displayed (see § 3.2). Note: The user can control the backlighting as required by pressing the key. -
