USING THE PRODUCT SAFELY
WARNING
!
CAUTION
!
■ Do not remove the product's covers and panels
Never remove the product's covers and panels for any purpose.
Otherwise, the user's electric shock or fire may be incurred.
■ Warning on using the product
Warning items given below are to avoid danger to user's body and life and avoid the damage or deterioration of the
product. Use the product, observing the following warning and caution items.
■ Warning items on power supply
● Power supply voltage
The rated power supply voltages of the product are 100, 120, 220 and 240VAC. The rated power supply voltage for
each product should be confirmed by reading the label attached on the back of the product or by the “rated” column
shown in the instruction manual. The specification of power cord attached to the products is rated to 125VAC for
all products which are designed to be used in the areas where commercial power supply voltage is not higher
than 125VAC. Accordingly, you must change the power cord if you want to use the product at the power supply
voltage higher than 125VAC. If you use the product without changing power cord to 250VAC rated one, electric
shock or fire may be caused. When you used the product equipped with power supply voltage switching system,
please refer to the corresponding chapter in the instruction manuals of each product.
● Power cord
(IMPORTANT) The attached power cord set can be used for this device only.
If the attached power cord is damaged, stop using the product and call us or your local dealer.
If the power cord is used without the damage being removed, an electric shock or fire may be caused.
● Protective fuse
If an input protective fuse is blown, the product does not operate. For a product with external fuse holder, the fuse
may be replaced. As for how to replace the fuse, refer to the corresponding chapter in the instruction manual.
If no fuse replacement procedures are indicated, the user is not permitted to replace it. In such case, keep the
case closed and consult us or your local dealer. If the fuse is incorrectly replaced, a fire may occur.
■ Warning item on Grounding
If the product has the GND terminal on the front or rear panel surface, be sure to ground the product to safely use it.
■ Warnings on Installation environment
● Operating temperature and humidity
Use the product within the operating temperature indicated in the “rating” temperature column.
If the product is used with the vents of the product blocked or in high ambient temperatures, a fire may occur.
Use the product within the operating humidity indicated in the “rating” humidity column.
Watch out for condensation by a sharp humidity change such as transfer to a room with a different humidity.
Also, do not operate the product with wet hands. Otherwise, an electric shock or fire may occur.
● Use in gas
Use in and around a place where an inflammable or explosive gas or steam is generated or stored may result in an
explosion and fire. Do not operate the product in such an environment.
Also, use in and around a place where a corrosive gas is generated or spreading causes a serious damage to the
product. Do not operate the product in such an environment.
● Installation place
Do not insert metal and inflammable materials into the product from its vent and spill water on it.
Otherwise, electric shock or fire may occur.
USING THE PRODUCT SAFELY
■ Do not let foreign matter in
Do not insert metal and inflammable materials into the product from its vent and spill water on it.
Otherwise, electric shock or fire may occur.
■ Warning item on abnormality while in use
If smoke or fire is generated from the product while in use, stop using the product, turn off the switch, and remove the
power cord plug from the outlet. After confirming that no other devices catch fire, ask us or your local dealer.
■ Input / Output terminals
Maximum input to terminal is specified to prevent the product from being damaged.
Do not supply input, exceeding the specifications that are indicated in the "Rating" column in the instruction manual of
the product. Also, do not supply power to the output terminals from the outside.
Otherwise, a product failure is caused.
■ Calibration
Although the performance and specifications of the product are checked under strict quality control during shipment
from the factory, they may be deviated more or less by deterioration of parts due to their aging or others.
It is recommended to periodically calibrate the product so that it is used with its performance and specifications stable.
For consultation about the product calibration, ask us or your local dealer.
■ Daily Maintenance
When you clean off the dirt of the product covers, panels, and knobs, avoid solvents such as thinner and benzene.
Otherwise, the paint may peel off or resin surface may be affected. To wipe off the covers, panels, and knobs, use a
soft cloth with neutral detergent in it.
During cleaning, be careful that water, detergents, or other foreign matters do not get into the product.
If a liquid or metal gets into the product, an electric shock and fire are caused.
During cleaning, remove the power cord plug from the outlet.
Use the product correctly and safely, observing the above warning and caution items.
Because the instruction manual indicates caution items even in individual items, observe those caution items to correctly
use the product.
If you have questions or comments about the manuals, ask us or E-Mail us.

Advanced
measurement
Advanced measurement (page19) mainly refers to the operation using the result
obtained from one or more of the basic measurement.
Background
Refresh rate defines how frequently the DL-2052 captures and updates the
measurement data. Faster refresh rate yields lower accuracy and resolution.
Slower refresh rate yields higher accuracy and resolution. Consider these
trade-offs when selecting the refresh rate.
Range

next.
2. The refresh rate indicator shows the current
status.

Background
The reading indicator next to the 1st display flashes according to the
refresh rate setting.
When no data is captured
When there is no captured data, the reading indicator flashes once every two
seconds (slower than the normal refresh rate), indicating the DMM is in the
waiting mode.
Automatic triggering
(default)
The DL-2052 triggers according to the refresh rate. See the previous page for
refresh rate setting details.

Background
Crest factor is the ratio of the peak signal amplitude to the RMS value of the
signal. It determines the accuracy of AC measurement.
If the crest factor is less than 3.0, voltage measurement will not result in error due
to dynamic range limitations at full scale.
If the crest factor is more than 3.0, it usually indicates abnormal waveform as
seen from the below table.

Measurement type
2-wire
Uses the standard V-COM ports.
Recommended for measuring resistances larger than 1kΩ.
4-wire
Compensates the test lead effect using the 4W compensation
ports, in addition to the standard V-COM ports.
Recommended for measuring sensitive resistances smaller
than 1kΩ.
1. Activate resistance
measurement
For 2-wire resistance measurement, press the
2W/4W key once.
For 4-wire resistance measurement, press the
2W/4W key twice.
2. 2W resistance mode

3. Connect the test lead
and measure
Connect the test lead. For 2-wire resistance, use the Ω (V) and the COM port.
For 4-wire resistance, use the Ω (V) and the COM port, plus the 4W sense, and
LO port for sensing. The display updates the reading.
