5.1 Inspection, Repair, and Cleaning

Do not attempt to modify, disassemble or repair the instrument; as fire, electric shock

and injury could result.

Transporting

Observe the following precautions to avoid damaging the instrument:

• Use the original packing materials when transporting the instrument, if possible.

• When sending the instrument for repair, remove the batteries and pack carefully to pre-

vent damage in transit. Include cushioning material so the instrument cannot move within

the package. Be sure to include details of the problem. Hioki cannot be responsible for

damage that occurs during shipment.

• Remove pens and recording paper when transporting the instrument. Failure to do so

may damage the hardware in the instrument that accommodates the pens and recording

paper due to vibrations. Be sure to cap the pens.

Storing the Instrument

• To avoid corrosion and damage to this instrument from battery leakage, remove the bat-

teries from the instrument if it is to be stored for a long time (for a month). For more infor-

mation about batteries, see "2.4 Connecting the Power Source (Alkaline Batteries or AC

Adapter)" (p. 17).

• Cap pens after use. Leaving pens uncapped may cause their tips to dry out, making it

impossible to record waveforms. When not being used, pens should be stored at room

temperature, avoiding high heat and humidity. For more information about storing pens,

see "2.3 Installing the Pens" (p. 16).

5.1 Inspection, Repair, and Cleaning

Useful life depends on the operating environment and frequency of use. Operation cannot be guar-

anteed beyond the following periods. For replacement parts, contact your dealer or Hioki represen-

tative.

The fuse is housed in the power unit of the instrument. If the power does not turn on, the fuse may be blown.

If this occurs, a replacement or repair cannot be performed by customers. Please contact your dealer or Hioki

representative.

To clean the instrument, wipe it gently with a soft cloth moistened with water or mild detergent.

Never use solvents such as benzene, alcohol, acetone, ether, ketones, thinners or gasoline, as they

can deform and discolor the case.

The CH2 pen will operate when the CH2

POWER switch is in the ON position.

Paper is not being

fed through the in-

strument.

Has the recording paper come off the

sprockets?

Verify that the recording paper has been

loaded properly (p. 14).

If the paper is not being fed through the in-

strument even though it has been loaded

properly, the instrument may be damaged.

A power protection component may

be damaged.

Customers should not attempt to replace or

repair parts. Contact your dealer or Hioki

representative for service.

The waveform is not

changing.

Are the cables connected properly? Verify that the measurement and other ca-

bles are connected properly.

Is the measurement range set proper-

ly?

Verify that the RANGE knob and the mV/V

switch have been set appropriately.

Is the ZERO/MEAS switch set to the

MEAS position?

Verify that the ZERO/MEAS switch is set to

the MEAS position and that the START/

STOP/FEED switch is set to the START po-

sition.

Nothing prints on the
