Specifications
Measures or sources Hz, kHz, CPM, CPH and pulses. It is
the ideal instrument for process technicians and electronic engineers, providing a highly accurate calibration
standard and versatile test tool. Dedicated features facilitate test and maintenance of electronic circuits and frequency instruments including frequency meters, batch
counters, tachometers, motion pickups, integrators and
flowmeters.
DPI 841 Frequency Loop Calibrator
Automatic Trigger
Detects the best value regardless of waveform or
amplitude
Frequency Scaling
Reads in process units; e.g. flow or revolutions/minute
Programmable Step and Ramp Outputs
Simplify calibration and diagnostics
Adjustable “Nudge” Value
Provides an incremental output for setting switches,
relays, trips and alarms
Advanced Features
Hold, maximum/minimum/average (with time stamp),
scaling, tare (offset) and damping f ilt er facilitat e syst em
checks and troubleshooting
Dual Readings
Provides simultaneous frequency output and mA measurement for transmitter and loop maintenance
24 V Power Supply
Energize transmitters and control loops
Automatic Switch Test
Captures open/closed trip values providing a fast and
highly accurate “safety system” check
HART Resistor
Can be switched into the loop when required for a HART
digital communicator and avoids the inconvenience of
carrying a 250 S resistor
