• Easy to use

With the Model 541 you can check & calibrate all your frequency instruments and measure flow

sensors.

• Take it into the shop, plant or field

Carry it without worry - it comes with a carrying case and fits into your toolbox.

Accurate to ±0.005% of range.

• Calibrate in Hz, kHz , CPM and CPH

0.001 to 20.000 kHz

0.1 to 2000.0 Hz

0.01 Hz to 200.00 Hz

0.1 to 2000.0 CPM (Counts-per-Minute)

1 to 20000 CPH (Counts-per-Hour)

• Quickly output the frequency you need

Simulate vibration pickups and variable

speed drives with sine wave outputs and

flow meters and magnetic pickups with

square wave outputs. If you calibrate positive

displacement flow meters, Watt-hour meters

or slow rated integrators select frequencies

as slow as 1 CPH (0.0002777 Hz). Easily set

any value quickly to within 0.01 Hz with the

two speed adjustable EZ-Dial™ plus store

any three frequencies for instant recall with

the EZ-Check™ switch. Verify optical pickups

with the GATE TIME LED that is

synchronized with the output pulses.

• Match your instrument signal levels

Choose zero based or zero crossing square

or sine waves output from 0.1 V to 12 V

peak-to-peak. Measure from 0.1 V to 120 V

peak with X1 or X10 attenuation. Turn the

dial to adjust the output amplitude to the

level required.

• Read signals from flow meters

Measure flow meter, vibration, parts counter

and other process frequency signals from

0.1 V to 120 V. GATE TIME LED flashes with

received pulses indicating when the proper

input adjustment level is achieved.

• Calibrate totalizers without a stopwatch

Automatically output from 1 to 99999 pulses in 1 to 100 minutes. Easier and more accurate than

waiting around with the stopwatch to stop generating pulses at the correct time. Count input

pulses from 1 to 100 minutes to verify totalizer input signals.
