Hioki 7016 Operation Manual
Hioki 7016 is an advanced signal source capable of generating a variety of signals, including constant voltage, constant current, and pulse. It also offers a SCAN function for outputting sequential values and a RAMP function for simulating linear waveforms. With its wide range of features and high accuracy, the Hioki 7016 is ideal for applications such as flow meter calibration, checking and calibrating counters, rotation counters, oscilloscopes, frequency converters, and other frequency-input systems.

3.3 Relative (relative display) Function
3.3 Relative (relative display) Function
The function applies to all measurement functions, subtracting a reference value from the measured value and displaying the calculated result.
In what situations is it used?
• When you want to zero out the internal resistance of probes
• When you want to read only the difference (offset) of a measured value from another value
• When you want high-accuracy measurement in the 50 mV DC or DCA ranges
Procedure
1.
Press the [
REL
] button to activate the Relative function.
appears on the display.
At this point,
• The displayed value becomes the reference for subsequent measurements, and is redisplayed as zero.
• If measured data is at overload level, [OL] appears on the display.

Press the [
REL
] button again to cancel the Relative function. disappears from the display
3.4 1-ms Peak Hold Function
39
3.4 1-ms Peak Hold Function
• Works with voltage and current measurement functions
• Shows the peak value of an input signal waveform
In what situations is it used?
Use to determine the crest factor of a waveform, where
crest factor = waveform peak value / true rms value
Procedure
1.
Hold the [
AC/DC
] button for one second to activate the 1-ms Peak
Hold function.
appears on the display.
At this point,
• The measurement displayed when the function was activated is held (retained).
• If auto-ranging was enabled, manual ranging is activated with the currently operative range retained.
