5.3. Resistance measurements (C.A 6523 and C.A 6525)
■ Start up the instrument by setting the switch to 400 kΩ.
■ Connect the + and - leads to the measurement points.
■ The user can control the backlighting as required by press-
ing the key .
■ Note the resistance value displayed (see § 3.3).
On the C.A 6523 and C.A 6525, an alarm threshold can be
activated using the ALARM key (see § 4.5).
6. CHARACTERISTICS
The instrument displays a measurement every 400 ms, which
corresponds to 2.5 measurements per second for the digital
display. The bargraph is refreshed every 100 ms. The digital
measurement is smoothed, while the bargraph always indicates
the instantaneous measurement.
