What drive capability is available when sourcing mA from internal power?

With internal battery operation it delivers up to 24V compliance or drives 1,200Ω at 20mA for loop testing.

How does it handle external loop simulation with a higher-voltage supply?

When simulating with an external 15V–48V loop supply it can drive up to 1000Ω at 20mA and supports over-range to 24.000mA.

Which measurement functions extend beyond current sourcing?

It measures AC/DC volts, AC/DC current, resistance, frequency to 20kHz, continuity and diode drop for broad diagnostic use.

How is data logging or wireless monitoring supported?

Wireless data logging is possible via a compatible adapter module that enables remote monitoring and upload to desktop or mobile tools.

What environmental tolerances exist for storage and transport?

It tolerates storage temperatures from -40°C to 60°C and survives a 1m drop test and random vibration at 2g (5–500Hz).
