Fluke Digital Multimeter, 1000V Maximum Test Voltage, 20mA Test Current - FLUKE-789/771 GEAR
This digital multimeter combines a safety-rated handheld DMM with mA loop functionality for troubleshooting and calibration in industrial environments. It measures AC/DC volts and current, resistance, frequency and continuity, and can source or simulate 0-20mA loops while operating from battery power. The instrument is suitable for field technicians who need a single portable tool that supports current loop diagnostics and routine electrical measurements.
Features and Benefits:
• 0.05% 20mA sourcing accuracy for precise loop calibration
• 1000V maximum test voltage for high-voltage diagnostics
• CAT IV 600V/CAT III 1000V safety rating for industrial environments
• True-rms measurement to 1000V for accurate AC readings
• Four AA battery operation providing 140 h typical runtime
• Frequency measurement to 20 kHz for signal verification
• 1000V maximum test voltage for high-voltage diagnostics
• CAT IV 600V/CAT III 1000V safety rating for industrial environments
• True-rms measurement to 1000V for accurate AC readings
• Four AA battery operation providing 140 h typical runtime
• Frequency measurement to 20 kHz for signal verification
Applications
• Suitable for commissioning current loop transmitters and sensors
• Ideal for maintenance of industrial control loops and PLCs
• Used for field verification of AC power and signal integrity
• Can be used for on-site resistance and continuity checks
• Used with HART-enabled loops when loop power and resistor required

What loop power capabilities are available when supplying a loop?
One variant provides a minimum 24 V loop supply capable of driving 250 Ω at 20 mA for powering field devices.
How does it behave when sourcing current into higher impedance loops?
In internal battery sourcing mode it supplies up to 24 V compliance and will drive 1,200 Ω at 20 mA.
What environmental range supports field use across seasons?
It operates between -20 °C and 55 °C and can be stored from -40 °C to 60 °C for varied site conditions.
Which measurement modes assist in capturing transient behaviour?
Min/Max/Average/Hold and Relative modes are available to Record and analyse variable signals.
What protection exists for jack-to-earth voltage exposure?
The maximum voltage that may be applied between any jack and earth is 1000 V RMS.
