Measurement categories (Overvoltage categories)

This product conforms to the safety requirements for CAT I measurement products.

To ensure safe operation of measurement products, 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 I : Secondary electrical circuits connected to an AC electrical outlet through a transformer or similar device.

CAT II : Primary electrical circuits in equipment connected to an AC electrical outlet by a power cord (portable tools, household appliances, etc.)

CAT III : Primary electrical circuits of heavy equipment (fixed installations) connected directly to the distribution panel, and feeders from the distribution panel to outlets.

CAT IV: 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 product designed for CAT III environments can endure greater momentary energy than one designed for CAT II. Using a measurement product in an environment designated with a higher-numbered category than that for which the product is rated could result in a severe accident, and must be carefully avoided.

Never use a CAT I measuring product in CAT II, III, or IV environments.

The measurement categories comply with the Overvoltage Categories of the IEC60664 Standards.

Precautions

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

			The floating voltage between input terminals and
	DANGER
			ground is 450V DC/AC. Attempting to measure
			voltages exceeding 450V with respect to ground
			could damage the product and result in personal
			injury.
			When voltages higher than 30 Vrms, 42.4 Vpeak or
			battery circuits with more than 60 VDC are to be
			measured, be sure to establish the floating state
			first. Carrying out such measurements in the
			grounded state involves the risk of electric shock.
			When measuring batteries, always ensure sufficient
			ventilation. Sometimes sparks may occur when the
			test leads are connected to batteries, which can
			ignite any accumulated inflammable gases such as
			hydrogen.
			To avoid electric shock accidents, when measuring
			batteries being charged wear proper protective gear
			such as rubber gloves.
			Do not allow the product to get wet, and do not take
	WARNING		measurements with wet hands. This may cause an
			electric shock.
			Do not use the product where it may be exposed to
			corrosive or combustible gases. The product may be
			damaged or cause an explosion.

Precautions

vi

___________________________________________________________________

				Before using the product, make sure that the
		WARNING
				insulation on the leads is undamaged and that no
				bare conductors are improperly exposed. Using the
				product in such conditions could cause an electric
				shock, so contact your dealer or Hioki representative
				for replacements. (Model 9460)
				Be sure to connect the SOURCE and SENSE
				terminals (banana plugs), and TEMP SENSOR
				terminal (mini-plug) correctly. See Section 4.2,
				"Measurement" for details of the connections.
				To avoid injury or damage to the product, do not
				attempt to measure AC voltage, or DC voltage
				exceeding 50 V.

50 VDC max.

Do not apply a voltage between the SOURCE(+) and SENSE(+) or SOURCE(-) and SENSE(-) terminals. This could result in damage to the unit.

CAUTION This product is not designed to be entirely wateror dust-proof. To avoid damage, do not use it in a wet or dusty environment.

___________________________________________________________________

Precautions

vii

___________________________________________________________________

CAUTION 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. Do not use the product near a device that generates a strong electromagnetic field or electrostatic charge, as these may cause erroneous measurements.

NOTE	Use the specified 9460 CLIP TYPE LEAD WITH
	TEMPERATURE SENSOR when this tester is used.

Correct measurement may be impossible in the presence of strong magnetic fields, such as near transformers and highcurrent conductors, or in the presence of strong electromagnetic fields such as near radio transmitters.

Service

Before using the product the first time, verify that it operates normally to ensure that the no damage occurred during storage or shipping. If you find any damage, contact your dealer or Hioki representative.

When sending the product for repair, remove the batteries and pack carefully to prevent damage in transit. Include cushioning material so the product cannot move within the package. Be sure to include details of the problem. Hioki cannot be responsible for damage that occurs during shipment.

Chapter 1

Overview

The 3550 is designed for measuring the internal resistance, open-circuit voltage, and terminal temperature of secondary batteries, including lead-acid batteries, nickel-cadmium batteries, nickel-metal hydride batteries, and lithium-ion batteries.

Features

	Since it uses the AC four-terminal method to measure the
	internal resistance, it provides accurate results with the lead
	resistances and contact resistances eliminated.
	It is possible to display the readings for the battery internal
	resistance, voltage, and terminal temperature, without
	changing functions. Moreover, a composite comparator
	function, which can be set on resistance and voltage values,
	enables reliable detection of battery deterioration.
	The unit's memory function also allows a number of sets of
	readings to be stored at a touch, and later output to a
	printer.
	These functions make this an ideal tool for checking
	batteries which are under constant trickle charging and
	cannot be disconnected.
	Measurements are taken by using noise reduction technology to
NOTE
	attenuate noise at frequencies other than the measurement
	frequency (1 kHz). Incorrect measurements may result if a large
	1-kHz noise component from the charger is present at the battery
	terminals.
