In order to ensure the safety of the user, IEC 60664 defines the ranges of use of
measuring instruments by classifying power levels into measurement categories
II through IV and O (None, other). This is because the excessive impulse or surge
levels induced in a power line vary depending on the location of measurement
(category). Categories
with higher numerals
designate locations that
include larger surge
voltages. Instruments that
are designed for category
III can thus withstand
higher surge voltages than
instruments designed for
category II.

Digital multimeters (DMMs) employ an A/D converter with a dual-integration
system, which determines the measurement value by converting the input
voltage into time using an integration AD converter. The interval to perform
an integral action periodically is referred to as the integralaction time.
Refers to a characteristic that shows variations in input, measurement, or
response with frequency. When measuring alternating current signals, a
measured signal does not have a simple frequency, but often includes
various frequencies ranging from lower frequencies to higher harmonics.
To measure such signals more accurately, it is preferable to use a
measurement device that has a broader frequency characteristic range.
To prevent the measured object from being influenced during voltage
measurement, you should use a measurement device with an extremely
high input impedance.
A unit used for describing the change in electrical signal amplitude or noise
level, or transmission systems in wired devices, etc. This parameter is also
used to represent the level differences in voltage, current or related values,
but is generally restricted to cases characterized by the relationship: (I

. In the abbreviation "dB," "d" (deci) denotes 1/10, and "B"
(Bell) denotes logarithm.
The products of Yokogawa Meters & Instruments Corporation are subjected
to design and evaluation testing to ensure compliance with the safety and
EMC standards in accordance with the directives issued by the EC.
The parameters EMI and EMS are referred to as electromagnetic
compatibility as they relate to compatibility within an electromagnetic
environment.
These standards lay out safety requirements that are to be met by a product
with the objective of the preservation of human life and property. The
applicable international standard is IEC 61010, and while a product must
conform to this standard, there are also domestic standards laid out by
individual countries. With these safety regulations, the range of use of a
measurement device is specified by categorization in measurement categories
I through IV to ensure the safety of the user. The designations "CAT II,
1000 V" or "CAT III, 600 V" at the input terminals of a measurement device,
for example, indicates the applicable category and the maximum voltage for
the device in terms of safety.
With DMMs, the measurement accuracy is generally expressed as: ±__% of
reading + __digits. ("Reading" refers to the reading value, and is abbreviated
as "rdg"; "digits" refers to the number displayed in the smallest decimal
place, and is abbreviated as "dgt.") This expresses the range of values that
a DMM may measure or represent for a given actual value.
The value most directly related to the energy of a given waveform. Refers to
the square root of a value found by averaging the squares of instantaneous
values of a waveform over a single cycle. (See Table 1,Figures 1 and 2.)
Refers to the average of the sum of instantaneous values, determined for a
current half-wave. It is equivalent to calculating the surface area of a
waveform.
Ratio of RMS value with respect to average value.
Form factor = RMS value/mean value (See Figures 1 and 2.)
Ratio of maximum value to RMS value.
Crest factor = maximum value/RMS value(See Figures 1 and 2.)
Refers to the distance between the smallest and largest amplitudes in a
waveform (see Figure 1).

Duty ratio (%) measurement
AC+DC measurement
Measures RMS of a waveform in which ripple waveforms are superimposed
on a direct current.
Supports waveforms of 1 ms or greater. You can capture instantaneous crest
values not possible with ordinary maximum measurement functions.
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.
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.

process it using application software or spreadsheet software (Excel*2) for
data management.

■ Reliability
High accuracy and safety
Accuracy: 0.09% rdg + 2 dgt (DC voltage)
True RMS measurement
Only TY530 can switch RMS and mean detection.
Conforms to EN61010-1 safety standard.
Shutters prevent erroneous insertion of test leads into current
measurement terminals (terminal shutters).
Conforms to overvoltage category 1000 V AC/DC, CAT Ⅲ and 600 V
AC/DC, CAT IV.
If the function is switched to other than current measurement while a test
lead remains inserted in a current measurement terminal, the fuse built into
the DMM can not protect the circuits. The terminal shutters prevent such
accidental errors.
The TY series, simply performing special operations via front panel allows
for quick and reliable adjustment. In addition, the series allows for one-
touch adjustment of AC voltage- and AC current-to-frequency
characteristics. The user calibration function leads to improved operation
efficiency and cost reduction.
• External standard instrument required for calibration.
The DMM can directly read the various sensor output signals (mV DC/AC)
at any scaling. The units can be changed (16 units are available).
Output signal and scaled value are simultaneously displayed.
User calibration function
The optional communication package*
1
sold separately (Model 92015)
allows you to connect to a PC for transmitting large amounts of data that
cannot be saved in the DMM internal memory.
You can transmit the saved data from the internal memory to a PC and
process it using application software or spreadsheet software (Excel*
2
) for
data management.
For details of the application software, refer to page 7.
Real-time measurement

*3 The communication cable employs an infrared system, so the device is
electrically insolated.

Anode Cathode
Voltage/Resistance Measurement
The COM terminal and V/Ω terminal are used. To
measure a voltage, set the dial to voltage measurement.
To measure a resistance, set the dial to resistance
measurement. Some DMM models can also display the
frequency and calculated decibel value at the same time
when measuring an AC voltage.
During resistance measurement, it is
possible to switch the function to
checking of the continuity of the
measured circuit.
Current Measurement
The COM terminal, and A, µA or mA terminal are used.
Some models have shutters for preventing erroneous
insertion into the current terminals and allow a contact of
a lead to a current terminal only when the dial is set to
current measurement. For these models, you cannot set
the dial to voltage measurement while
a lead is left inserted into a current
terminal. This feature provides greater
safety.
Diode Test
A current flows through a diode when the power supply is
connected as (1) below, while, almost no current flows
when the power supply is connected as (2). The diode
test function applies an adequate forward voltage across
a diode to make a constant current flow and measures
the voltage drop in the forward direction
to determine the forward and reverse
directions of the diode.
