MTX 3281
In this position, you measure the value of a resistance.
MTX 3282
MTX 3283
Automatic/manual range selection
"Active" protection via CTP thermistor
Measurement voltage: ca. 1.2 V
Maximum voltage developed on open circuit: 4 V typ

In range 50 M Ω , in order to avoid the influence of the network and to guarantee the
given specifications, it is advised to disconnect the multimeter from Wall Plug.

For measurements higher than 10 M Ω , a shielded cable is recommended.
For a 2 wire-link, use very short wires (< 25 cm) and twist them.
Continuity Mode ( )
MTX 3281
MTX 3282
MTX 3283
On this position, you can measure the value of a resistance up to 1000 Ω, with
steady audio indication at 2 kHz.
Detection threshold in continuity mode ≈ 120 Ω (response time ≈ 5 ms).
"Active" protection via CTP thermistor.
Maximum voltage on open circuit: 4 V max, 2 V typ.
