DANGE

This product is designed to conform to IEC 61010 Safety Standards, and has been thoroughly tested for safety prior to shipment. However, mishandling during use could result in injury or death, as well as damage to the product. Be certain that you understand the instructions and precautions in the manual before use. We disclaim any responsibility for accidents or injuries not resulting directly from product defects.

・This symbol is affixed to locations on the equipment where the

operator should consult corresponding topics in this manual (which are also marked with the

symbol) before using relevant

functions of the equipment.

・In the manual, this mark indicates explanations which it is

particularly important that the user read before using the equipment.

Indicates a grounding terminal.

Indicates AC (Alternating Current).

Indicates DC (Direct Current).

Indicates both DC (Direct Current) and AC (Alternating Current).

Indicates the ON side of the power switch.

Indicates the OFF side of the power switch.

afety Notes

This manual contains information and warnings essential for safe operation of the product and for maintaining it in safe operating condition. Before using the product, be sure to carefully read the following safety notes.

Safety symbols

Accuracy

We define measurement tolerances in terms of f.s. (full scale), with the following meanings:

f.s. (maximum display value or scale length)

The maximum displayable value or scale length. This is usually the name of the currently selected range.

────────────────────────────────────────────────────

Safety Notes

────────────────────────────────────────────────────

DANGE

Indicates that incorrect operation presents extreme danger of accident resulting in death or serious injury to the user.

WARNIN

Indicates that incorrect operation presents significant danger of accident resulting in death or serious injury to the user.

CAUTIO

Indicates that incorrect operation presents possibility of injury to the user or damage to the equipment.

NOTE

Denotes items of advice related to performance of the equipment or to its correct operation.

Conventions used in this manual

The following symbols are used in this Instruction Manual to indicate the relative importance of cautions and warnings.

Measurement categories (Overvoltage categories)

This instrument complies with CAT II safety requirements. To ensure safe operation of measurement instruments, IEC 61010 establishes safety standards for various electrical environments, categorized as CAT I to CAT IV, and called measurement categories. These are defined as follows. CAT

: Secondary electrical circuits connected to an AC electrical outlet

through a transformer or similar device.

CAT

: Primary electrical circuits in equipment connected to an AC electrical

outlet by a power cord (portable tools, household appliances, etc.)

CAT

: Primary electrical circuits of heavy equipment (fixed installations)

connected directly to the distribution panel, and feeders from the distribution panel to outlets.

CAT

: The circuit from the service drop to the service entrance, and to the

power meter and primary overcurrent protection device (distribution panel).

Higher-numbered categories correspond to electrical environments with greater momentary energy. So a measurement device designed for CAT III environments can endure greater momentary energy than a device designed for CAT II. Using a measurement instrument in an environment designated with a higher-numbered category than that for which the instrument is rated could result in a severe accident, and must be carefully avoided. Never use a CAT I measuring instrument in CAT II, III, or IV environments. The measurement categories comply with the Overvoltage Categories of the IEC60664 Standards.

────────────────────────────────────────────────────

Notes on Use

────────────────────────────────────────────────────

WARNIN

Do not use the product where it may be exposed to corrosive or combustible gases. The product may be damaged or cause an explosion.

CAUTIO

・This product should be installed and operated indoors only, between 5 and

40℃ and 35 to 80% RH.

・Do not store or use the product where it could be exposed to direct sunlight,

high temperature or humidity, or condensation. Under such conditions, the product may be damaged and insulation may deteriorate so that it no longer meets specifications.

・This product is not designed to be entirely water- or dust-proof. To avoid

damage, do not use it in a wet or dusty environment.

WARNIN

Before turning the product on, make sure the source voltage matches that indicated on the product’s power connector. Connection to an improper supply voltage may damage the product and present an electrical hazard.

Before making connections, make sure the 9439 DC POWER ADAPTER is turned off. The 8835-01 could be damaged by a spark if it is connected to a voltage source while its power supply is on.

WARNIN

To avoid electric shock and ensure safe operation, connect the power cable to a grounded (3-contact) outlet.

otes on Use

Follow these precautions to ensure safe operation and to obtain the full benefits of the various functions.

(1) Installation environment

(2) Power supply connections

・Check that the power supply is correct for the rating of the unit. (The AC

fuse is integrated in the unit.)

・The AC power power switch on 8835-01 is for AC power. If DC power is

being supplied and the switch on DC power adapter is set to ON, the 883501 will operate also if the power switch is set to OFF.

(3) Grounding the unit

DANGE

Maximum input voltage ratings for the 8936 ANALOG UNIT, 8937 VOLTAGE/TEMP UNIT, 8938 FFT ANALOG UNIT, 8939 STRAIN UNIT 8940 F/V UNIT, 8946 4ch ANALOG UNIT, 8947 CHARGE UNIT and input terminals of the 8835-01 are shown below. To avoid the risk of electric shock and damage to the unit, take care not to exceed these ratings.

The maximum rated voltage to earth of the 8936, 8937, 8938, 8939, 8940, 8946 and 8947 (voltage between input terminals and 8835-01 frame ground, and between inputs of other input units) is shown below. To avoid the risk of electric shock and damage to the unit, take care that voltage between channels and between a channel and ground does not exceed these ratings.

The maximum rated voltage to earth rating applies also if an input attenuator or similar is used. Ensure that voltage does not exceed these ratings.

When measuring power line voltages, 8936 or 8938 should only be connected to the secondary side of a breaker, so the breaker can prevent an accident if a short circuit occurs. Connections should never be made to the primary side of a breaker, because unrestricted current flow could cause a serious accident if a short circuit occurs.

Always use the optional connection cables. Any exposed metal sections

in a connection cable consist a risk of electric shock.

Notes on Use

────────────────────────────────────────────────────

DANGE

Logic probe input and 8835-01 share the same GND. Separate power supply sources applied to the testing device and 8835-01 may result in risk of electric shock and damage to the unit. Even with the same power supply source, certain ways of wiring may cause a variance in electric potential sending current that may damage testing device and 8835-01. The following shows proper wiring to avoid damage. For details, see Section 2.5.

(1) Before connecting logic probe to testing device, connect grounded

three-core power cord (attachment) to the device to be tested and 8835-01 and supply power from the same outlet.

(2) Before connecting logic probe to device to be tested, connect GND of

device to be tested with 8835-01 functional ground terminal. Make sure that power is supplied from the same outlet.

When using grabber clips, the 9322’s maximum rated voltage to earth is 1500 V AC/DC; when using alligator clips, it is 1000 VAC/DC. To avoid electrical shock and possible damage to the unit, never apply voltages greater than these limits between the input channel terminals and chassis, or across the inputs of two 9322s.

Maximum input voltage is 1000 VAC/2000 VDC. Do not measure voltage in excess of these limitations, as doing so may damage the unit or cause an accident that might result in injury or death.

CAUTIO

・Use designated connection cables only. Other cables may interfere with

proper connection and measurement accuracy.

・Maximum charge input for miniature connecter terminal in 8947 CHARGE

UNIT is +, - 500 pC (at range 6 high sensitivity) and +, - 50000 pC (at range 6 low sensitivity).

NOTE

WARNIN

･ Always put the unit in the head up condition when it is to be transported or if

it is to be stored for a long period of time. If the unit is left to lie in the state where the roller is being subjected to pressure by the head, then the roller may become deformed or the characters may become uneven.

･ Particularly care should be taken not to put the recording paper in back to

front by mistake, because if this happens the waveform cannot be drawn.

･ Printing is not possible if the recording paper is loaded wrong-side up. ･ Do not insert it into the gap between the roller and the black sheet metal

portion.

･ Refer to the illustration to make sure that the correct side of the recording

paper is facing up.

･ Do this very carefully, because if the recording paper is slanted with respect to

the roller there is a danger that later a paper jam will occur.

.8 Storage and Handling Precautions

Store rolls of thermal paper at no more than 40℃. The paper will change color if exposed to light over a long period, so do not unwrap a roll of paper until you are ready to use it.

Storing data recordings

As the recording paper is thermally sensitive, be aware of the following points:

・To avoid paper discoloration, do not expose it to direct sunlight, and store at

no more than 40℃ and 90% RH.

・For permanent storage of important recorded data, photocopy the recording

paper.

・If the thermal paper is exposed to an organic solvent such as alcohol or

ketone, it may no longer develop properly, and recorded data may fade.

DANGE

In order to avoid accidents from electric shock, before removing or replacing an input unit, check that the connection cables are disconnected, turn off the power, and remove the power cable.

Normally keep all input units installed permanently. If a unit is not fitted, it must be replaced by a blanking panel. If the unit is operated with an input unit not in place it poses a shock hazard.

When using grabber clips, the 9322’s maximum rated voltage to earth is 1500 V AC/DC; when using alligator clips, it is 1000 V AC/DC. To avoid electrical shock and possible damage to the unit, never apply voltages greater than these limits between the input channel terminals and chassis, or across the inputs of two 9322s.

Maximum input voltage is 1000 VAC/2000 VDC. Do not measure voltage in excess of these limitations, as doing so may damage the unit or cause an accident that might result in injury or death.

Once the RMS value is set to the required level, triggering occurs immediately. (When the RMS recorder function is used, triggering occurs even before pretriggering is set. In the example shown below, waveforms equivalent to 2 DIV (approximately 10 s) counted from initiation of measurement are recorded prior to triggering.

・When the waveform has been recorded for the specified recording length, the

LED goes off, and the unit enters the stop state. (The waveform below is printed, with the gauge function enabled on the SET UP (SYSTEM 1) screen.)
