OUTLINE
(Accuracy ±0.5%)
These four digital multimeters of the DL-90 Series have
been designed to meet the diversifying needs users
have for multimeters. Some of the most advanced
functions incorporated in these models include the
auto power-OFF function (which prevents wasting of
battery power even if you forget to switch the power
off) and current input connection alarm function which
generates an alarm buzzer sound if you attempt to
measure voltage while a test lead is left connected to
the current input. An analog bar display is provided
together with a digital display so the measurements
can be identified a glance. Naturally, all models offer
the basic measurement modes including DC voltage,
AC voltage, DC current, AC current, resistance, diode
checking and circuit continuity checking.

A 7-segment LCD display and a 40-segment bar graph display are
provided.
Versatile Measurement Modes
All fundamental measurements are available, including: DC V, AC
V, DC A, AC A, Ω as well as diode checking and continuity testing
modes.
Versatile Measurement Modes
In addition to the basic measurements including DC V, AC V, DC
A, AC A, Ω and plus diode checking and continuity testing modes,
frequency measurement and capacity measurement modes are
also available.
Auto Power-OFF
The auto power-OFF circuit prevents wasteful consumption of
batter y power even when you forget to switch power off after
measurement.
Auto Power-OFF
The auto power-OFF circuit prevents wasteful consumption of
batter y power even when you forget to switch power off after
measurement. In addition, it is also possible to defeat this circuit.
Auto/Manual Ranging Switchable
The measurement ranges in the DC V, AC V , Ω and
measurements can be switched either automatically or manually.
Auto/Manual Ranging Switchable
The measurement ranges in the DC V, AC V, Ω and
measurements can be switched either automatically or manually.
Data Hold
This function stops measurement temporarily and maintains the
previously-measured value on the display.
Battery Low Indication
When the voltage of the built-in batteries drops, the battery mark
blinks to alert you.
Relative Computations
This function calculates the difference from a reference value so
that, for example, it can eliminate the input lead resistance during
resistance measurement.
Data Storage/Recall
Measured data can be stored or recalled in memory together with
the measuring units.

Current Input Connection Alarm
When current measurement is switched to voltage measurement
and, if the test lead used is left connected to the current input,
hazard will occur because the measurement object is shor tcircuited at the moment the voltage measurement is started. To
prevent this, a buzzer beeps when a test is lead is connected to the
current input in measurement modes other than the current
measurement modes.

Maximum and Minimum Data Memory
The maximum and minimum values are stored in memor y. A
buzzer beeps every time one of these values is updated.

5000 Full-Scale Digital Display plus Analog Bar Graph
A 7-segment LCD display and a 50-segment bar graph display are
provided.
Back-lighted LCD Display
The back light can be turned on to allow easy checking of the
measured values even under low light.
Versatile Measurement Modes
In addition to the basic measurements including DC V, AC V, DC
A, AC A, Ω and plus diode checking and continuity testing modes,
the frequency measurement, capacity measurement and TTL logic
level judgment modes are also available.
Dual Display
Two measurement value display sections are provided so it is
possible to display the voltage and frequency or the DC and AC
components simultaneously.
4000/40000 Full-Scale Digital Display plus Analog Bar Graph
A 7-segment LCD display and a 20-segment x 4 bar graph display
are provided. The full scale can be switched to 40000 increasing
the display resolution by 1 digit.
True rms Measurement
AC V measurement measures tr ue rms values in place of
obtaining values by conversion from the average values.
Auto power-OFF function
The instrument enters sleep mode in 15 minutes and the power
goes OFF automatically in 15 more minutes. The auto power-OFF
function can also be defeated.
Versatile Measurement Modes
In addition to the basic measurements including DC V, AC V, DC
A, AC A, Ω and plus diode checking and continuity testing modes,
the frequency measurement, capacity measurement, duty cycle
measurement, pulse duration measurement and temperature
measurement modes are also available. It is also possible to
measure AC in which DCs are superimposed.
Maximum and Minimum Data Memory
The maximum and minimum values are stored in memory and
can be displayed. The elapsed time values at which these values
are obtained are also displayed alternately.
Average Value Computation
The average value of measured values can be calculated and
displayed. The elapsed time values are also displayed alternately.
High Accuracy/True rms Measurement
The accuracy is as high as ±0.6% of reading 3 digits with DC
voltage measurement. The AC V and AC C measurement
measures tr ue rms values in place of obtaining values by
conversion from the average values.
Relative Computations ( ∆, ∆/r)
The ∆mode calculates the difference from a reference value and
the ∆/r mode calculates the deviation when the reference value is
assumed to be 100%.
1 msec Peak Hold
The capability of capturing the waveform peak value makes it
possible to calculate the crest factor when combined with the true
rms measurement function.
dBm Measurement
The reference impedance can be selected from 20 selections
between 4 and 1,200Ω in addition to 600Ω.
Communications Function
The optional OP-597 allows the DL-97 to interface with a computer
through RS-232C and to store the data measured with it in the
computer.
TTL Logic Level Judgment
This function displays the identified RHS level with ▲ and the RLS
level with ▼.
Square Wave Output
The square wave frequency can be selected from 16 selections
between 0.5 Hz and 4.8 kHz. The duty ratio is also variable
between 1% and 99% in 1% steps.
