4.1.1.3 Measurement Function Keys
1. DCV Selects the DC voltage measurement (DCV).
2. ACV Selects the AC voltage measurement (ACV). The AC filter can be
selected from FAST, MED, and SLOW.
3. 2W/4W Selects the resistance measurement. Either 2W or 4W can be
selected alternately.
4. DCI Selects the DC current measurement (DCI).
5. ACI Selects the AC current measurement (ACI). The AC filter can be
selected from FAST, MED, and SLOW.
6. FREQ Selects the frequency measurement (FREQ)
7. Bch (SHIFT+DCV) Selects the DC voltage measurement (DCV-Bch).
8. AC + DC (SHIFT + ACV) Selects the AC+DC coupling or AC coupling in the AC voltage
measurement.
