715
787
789
715 Volt/mA Calibrator
Outstanding performance,
durability and reliability.
• Measure loop current (0-20 mA,
4-20 mA) signals with very
high accuracy of 0.015% and 1
mA resolution
• Measure voltage output process
signals from PLCs, transmitters
• Source or simulate 24 mA loop
current
• Source voltage to 100 mV or 10 V
• 24 V loop supply with simultane-
ous current measurement
• Enhanced voltage and current
measure and source accuracy
• NIST traceable calibration
787 ProcessMeter™
A complete troubleshooting
solution in the palm of your hand
with a digital multimeter and loop
calibrator in one tool.
• 1000 V overload protection
on V, ohms, frequency
• 150 V overload protection on
mA, backed up by 440 mA
1000 V fuse
• 25 % manual step plus auto
step and auto ramp on mA
output
• CAT III 1,000V rating
789 ProcessMeter™
The 789 includes all the popular
features of the 787 and adds:
• 24 V loop power supply
• 1200 ohm drive capability on
mA source
• HART mode setting with loop
power and a built-in 250 ohm
resistor
• 0 % and 100 % buttons to
toggle between 4 and 20 mA
sourcing for a quick span check
• CAT IV 600 V rating
771 Milliamp Process Clamp
Meter
Saves time by making fast, accu-
rate measurements on 4-20 mA
signal loops without breaking the
circuit.
• 0.01 mA resolution and
sensitivity
• Measure mA signals for PLC and
control system analog I/O
• Measure 10 to 50 mA signals in
older control systems using the
99.9 mA range
772 Milliamp Clamp Meter
Expanded features of the popular
771 mA Clamp Meter by adding
loop power and mA sourcing to
the capabilities.
• Measure 4 to 20 mA signals
with in-circuit measurement
• Simultaneous mA in-circuit
measurement with 24 V loop
power for powering and testing
transmitters
• Source 4 to 20 mA signals for
testing control system I/O or I/Ps
• Automatically ramp or step the
4 to 20 mA output for remote
testing
773 Milliamp Process Clamp
Meter
The premier mA clamp meter,
adds advanced troubleshooting
features and voltage source/
measure for testing voltage I/O.
Icludes all the features of the
772 plus:
• DC voltage sourcing and mea-
surement, verify 24 V power
supplies or test voltage I/O
signals
• Scaled mA output provides
a continuous mA signal that
corresponds to the 4 to 20 mA
signal measured by the mA
clamp
• Simultaneously source and
measure mA signals
