To measure
this value
The following settings apply to the GT-220 and GT-540:
Auto select AC volts,
DC volts, resistance,
and continuity*
(low impedance
measurement)
EF (electric field
detection)
The following settings apply to the GT-540 only:
AC voltage
(high impedance to
minimize loading)
DC voltage
(high impedance to
minimize loading)
Low resistance
(600 Ω), fast
continuity test
Diode, fast
continuity test
Capacitance†
* Tone indicates continuity. Threshold is 0.025 kΩ nominal.
** Refer to "Using the Features" for a detailed description of this mode.
† Discharge capacitor before measurement.
