Yokogawa 734 Series
50,000 count DMM with True RMS

High accuracy 0.04% at DC voltage and 50,000 count / 51-segments bar graph display. 73401 can be used for many types of situation such as electrical work, maintenance and R&D. IR communication allows easy management of measured data.
IR communication function
Internal memory function to store measured data
User calibration function
Shockproof elastomer casing
Safety shutters prevent erroneous insertion of test leads into current measurement terminals (so called "Terminal Shutters")
Memory function saves 50 data in manual-mode memory & 600 data in logging-mode memory (73402 Only)

4.5 digits (50,000-count, 51-segment bar graph display), RMS type Measurement Functions: Voltage, Current, Resistance, Continuity Check, Diode Test, Frequency, Capacitance, Temperature Features: Internal memory, Communication function, User calibration function

Peak hold function (73402 Only, for DC V/A measurement)
Supports waveforms of 1 ms or greater. You can capture instantaneous crest values not possible with ordinary maximum measurement functions.

Relative and percentage value computation
Can display the measured values as the values relative to a reference value (defined by the REL key; even after data hold) or as the percentages of the reference value. Percentage calculation: (Measured value – reference value) / (reference value), expressed as percentage.

Duty ratio (%) measurement
Displays the duty ratio of a pulse waveform: High level period/1 cycle of waveform) x 100 = (t2/t1) x 100 [%]

AC+DC measurement
Measures RMS of a waveform in which ripple waveforms are superimposed on a direct current.

Auto hold
Automatically hold the data measured when the test leads are disconnected from the measured object, thus freeing both hands for performing reliable measurement.

Minimum/maximum/average display
Allows recording of minimum, maximum and average values along with their respective times (time passed since the start of measurement)

Decibel calculation
Computes the logarithm of an alternating current, and uses it together with the relative value computation to display the relative value. You can select the standard resistance according to the application, such as audio or communication circuit signal measurement.

50,000-count, 51-segment bar graph display
Allows simultaneous display of frequency and voltage, frequency and duty ratio or decibels and voltage on dual display. The 734-02 has a black-lit display for easier viewing.

Management with special application software
You can display measured data as a table and trend graphs. Real-time data transmission allows you to see moment-to-moment changes at a glance. In addition, when displaying DMM data on a PC screen they are enlarged to allow you to easily discern new data.
