Inspection/Maintenance

When you receive the product, inspect it carefully to ensure that no damage occurred during shipping. If damage is evident, or if it fails to operate according to the specifi cations, contact your authorized Hioki distributor or reseller.

Preliminary checks

Before using the product, ensure that the insulation on the probes are not damaged and conductors are not exposed. Using the product in such conditions could cause an electric shock, so contact your authorized Hioki distributor or reseller for repair.

Maintenance and service

Never use cleaning agents containing benzene, alcohol, acetone, ether, ketones, thinners or gasoline. These can deform and discolor the case.

To clean the product, wipe it gently with a soft cloth moistened with water or mild detergent.
If the product seems to be malfunctioning, contact your authorized Hioki distributor or reseller. Pack the product so that it will not get damaged during shipping, and include a description of existing damages. Hioki cannot be responsible for damage that occurs during shipment.

Disposal

Handle and dispose of the product in accordance with local regulations.

Operating Precautions

Installing the product in inappropriate locations may cause the probe to malfunction or lead to accidents. Please do not install in the following locations. For details on the operating temperature and humidity, see the specifi cations.

Exposed to direct sunlight or high temperatures
Exposed to corrosive or combustible gases
Exposed to strong electromagnetic fi elds or electrostatic charges
Near induction heating systems (such as high-frequency induction heating systems and IH cooking equipment)

Exposed to water, oil, chemicals, or solvents
Exposed to high humidity or condensation
Exposed to high quantities of dust particles

The ends of the probes are sharp. Be careful to avoid injury.
To prevent probe damage, do not step on probes or pinch them between other objects. Do not bend or pull on probes at their base.

Safety Information

Before using the product, be certain to carefully read the following safety notes.

Customers are not allowed to modify, disassemble, or repair the instrument. Failure to observe these precautions may result in fire, electric shock, or injury.
Ensure that the input does not exceed the maximum input voltage or current to avoid product damage resulting from heat building. Excessive voltage and current can cause the product to malfunction.

Mishandling could result in malfunction of the probe. Be certain that you understand the instructions and precautions in the manual before use.
If persons unfamiliar with electricity measuring product are to use the product, another person familiar with such instruments must supervise operations.

Accessories

Connection Method

Clean the tip of the tip pin and the surface of the measuring object before zero adjustment and measurement.

Connecting to the instrument

Connecting the return cable

Connect the return cable before measurement.
Adjust the fixed position of the probe so that the return cable between the probes does not sag.

Securely insert the plug of the return cable up to the back of the probe (both red and black).
Arrange the probes so that the distance between the pin tips of the probe is the same as that between the terminals of the actual measuring object, with the SENSE sides of the probes (both red and black) facing inwards.
Adjust the position of the probes such that the return cable between the probes does not sag, and fix by pushing the return cable into the grooves of the probes.

When viewed from the front

When viewed from the rear

(The return cable is indicated black in the illustration above.)

Use a cable of suitable length for the distance between the terminals of the measuring object from the three types of accessory cables.

Return cable length	Distance between the terminals of the measuring object
400 mm	100 mm or less
550 mm (mounted before shipment)	100 mm to 250 mm
800 mm	250 mm to 500 mm

Fixing Using

The probe can be fixed using the mounting holes. (Please prepare your own jig or equipment to fix.) Hole diameter: 3.2 mm, use a M3 screw.
Fixing Using

Zero Adjustment

Execute the zero adjustment using the zero adjustment board provided with the connected instrument. Insert the tip pins of the probes into through holes having the same width as the terminals of the measuring object, and carry out the zero adjustment with the connected instrument.

Adjust the return cable between the terminals so that it does not sag.
If there is no through hole with the same width as the terminals of the measuring object, perform zero adjustment with the most nearest width scale of the through hole as the terminals.
Perform zero adjustment by facing the probe's (both red and black) SENSE side inwards.

Replacing the Used Tip Pin

Replace the used tip pin with a new one when the tip pin breaks or is worn out. To purchase Model 9772-90 Tip Pin for replacement, contact your authorized Hioki distributor or reseller.

<Tools to be prepared> Model 9772-90 Tip Pin, pliers, etc.

Turn off the power to the connected instrument and remove the return cables of the probes.
Grip the tip pin to be replaced with pliers and pull it out.
Insert a new tip pin in the socket, and securely push to the back by pressing with a hard board so that the tip pin does not fl y out.
Measure a known measuring object to check if the measured value is correct.

Four-terminal Pair Method

L2003 uses the four-terminal pair method as the measurement method.

Four-terminal pair method

In the four-terminal pair method, the current fl ows backward (current returns) with the same magnitude as the measuring current in the shields of the SOURCE cables, and then cancels the magnetic fi eld of the measuring current. This method suppresses the induced electromotive force induced at the SENSE terminals, and detects the voltage actually generated in the object being measured.

Four-terminal pair method when using the optional probe

When the L2003 is used, the four-terminal pair method is structured as described below. Vicinity of the measurement object will not entirely be four-terminal pair, and will be affected by an inductive magnetic field. The shape of the return cable should not be changed, and kept away from metals when use. (When there are metals, inductive magnetic field occurs due to eddy current, and leads to measurement errors.)
Four-terminal pair method when using the optional probe

Keep the loop area between the return cable and measurementobject as small as possible.
Keep the loop shape and wiring position always the same.
Keep away from metals.

When the measurement value fluctuates

Keep the return cable in shape, or the affects of the magnetic field changes and the measurement value may flactuate.
Twist the return cable to keep a fixed shape.
(The return cable is indicated black in the illustration.)
