Chapter 1 Overview

1.1 Overview

The HT3554 series Battery Tester measures internal resistance, voltage, and terminal
temperature of lead-acid, nickel-cadmium, nickel-hydrogen, and other types of batteries,
enabling you to determine if the battery is worn out.

The measurement data can be copied to a computer by connecting the instrument to a computer

after measurement with the USB cable provided.

1.2 Features

Enables measurement without shutting down UPS systems(only HT3554)
This instrument uses high-precision AC resistance measurement technology. Time required

for measurement is reduced since the instrument is capable of measuring live wires without
requiring the UPS system to be shut down.

Reliable measurement values
This instrument is capable of obtaining reliable measurement values without being affected by

lead or connector resistance because it uses the AC 4-terminal method to measure internal
resistance.

Simultaneous display of resistance, voltage, and temperature
Without changing functions, this instrument can display battery internal resistance, voltage, and

terminal temperature simultaneously.
Comparator function
The comparator function enables you to set threshold values for internal resistance and voltage.

This can determine battery wear more easily.
Large memory capacity
This instrument can store up to 2400 sets of data combining presently measured values

(resistance, voltage, temperature, and comparator measurement results). It can be used to
measure up to 12 units of 200-cell cubicles.

Chapter 3 Basic Measurement

Before measurement, be sure to read this chapter.

To avoid electric shock accident and short circuit, please operate the instrument as following:

² Do not test the voltage over 70 VDC（HT3554）/100 VDC(HT3554A)/

300 VDC(HT3554B)/1000 VDC(HT3554D).

² Do not test the terminal-to-ground voltage over 70 VDC（HT3554）/

100 VDC(HT3554A)/300 VDC(HT3554B)/1000 VDC(HT3554D).

² Do not test AC voltage.

² If a voltage or current is applied beyond the rated range, the instrument will be damaged.
² After measuring the high voltage battery, you should put the test leads together and make

them shored first, and then test the low voltage batteries. In this way, the power of DC
cutoff capacitance can be removed, otherwise the overvoltage may damage the
low-voltage battery.

² Internal battery resistance varies considerably depending on charge or discharge status. To

increase measurement accuracy, make measurements under similar conditions (for
example, a fully charged battery).

² Lead-acid batteries (measuring objects) have high levels of terminal resistance. For this

reason, resistance values may differ between the case and the tip of the terminal. Be sure
to connect the test lead to the terminals at a fixed location.

² Use the optional Clip Type Lead with Temperature Sensor to measure the battery

temperature. Or, use a non- contact thermometer, such as a radiation thermometer, for
safety.

² Measurement may not be possible for insulated terminals, due to insufficient flow of

current for measurement. In such a case, clean the terminal (remove the insulation) before
measurement.

zero function before measurement.

² Performing zero adjustment adjusts the zero points of all ranges.
² It takes 5 seconds to perform the zero adjustment
² Even after the instrument is turned off, the correction values are retained and the zero

adjustment function is not canceled.

² After replacing the test lead, be sure to perform zero adjustment prior to measurement.
² Be sure to use the included zero adjustment block 9363-B when performing zero adjustment.
² Be sure to keep the test lead shorted during zero adjustment.

3.3.1 Shorting Methods for Various Test Leads

For Pin Type Leads 9363-B

23

9363-B pin type test lead

Be sure to connect each of the DRIVE and SENSE terminals by inserting the tip of the pin into the
holes on the zero adjustment board. (See the figure above.)
Do not place the zero adjustment board on top of the battery or any metal. Electromagnetic
induction effect could result in unstable measurement values. In such a case, keep the zero
adjustment board away from any metal.
Be sure to use the included zero adjustment board when performing zero adjustment.
When the distance between the terminals on the battery (measurement target) is more than the
distance between the holes on the zero adjustment board, use the holes at both corners to perform
zero adjustment.

For Clip Type Leads

Perform zero adjustment by engaging red and black clips together.

Chapter 9 Appendix

9.1 Effect of extended test line and induced voltage

Test lines can usually be extended by customization. If you want to extend the test line, please
contact the dealer or Hope Instrument. The user can not extend the test line privately.

Reduce induction voltage

Because the instrument under AC power to test resistance with very small resistance, the inductive
voltage will affect the test. The inductive voltage makes the current in the instrument produce
inductive coupling inside the wire, which will affect the in-line signal. Because the AC current
(reference signal) is 90 degrees different from the phase of the induced voltage, the synchronous
detector circuit can remove the induced voltage when the voltage is low. But when the voltage is
high, the inductive voltage will distort the signal and produce the wrong synchronous detection
signal. The instrument detects the internal inductive voltage, if the voltage rises to a certain height,
will produce the wrong test signal. Reducing the length of the test line, especially the length of the
branch part, will weaken the inductive voltage. When the standard test line is used, the induced

voltage will affect the deviation of the result value by about 15 dgt.. if the zero adjustment
and the test wiring are extremely different in 3 mΩ range.

9.2 Influence of Eddy Current

The AC current in the instrument will generate eddy current around the metal plate, and the
eddy current will generate inductive voltage inside the test line. Because the phase of the
induced voltage is 180 degrees different from the phase of the AC current (reference current),
the synchronous detection current cannot eliminate the induced voltage, which leads to a test
error. Eddy effect is unique to the ohmmeter of AC power supply. The distance between the
metal parts including the metal plate and the test line (branch part) should be reduced to avoid
the influence of eddy current.

50

9.3 AC 4-terminal Measurement Method

The instrument uses AC four-terminal measurement method, so when measuring resistance,
it is not necessary to consider the internal resistance of the test line and the contact
resistance between the test line and the object under test.

The AC current (Is) flowing from the SOURCE port of the instrument flows through the
tested battery. The voltage drop (VIS) of the internal resistance of the battery is measured
by the SENSE port. At this point, since the SENSE port is connected to an internal voltmeter
with a high impedance, there is no current passing on the R2 and R3 representing the
resistance and contact resistance in the test line. Therefore, there is no voltage drop on
the resistance R2 and R3, because the voltage drop of the resistance and contact
resistance in the test line is very small, which can be ignored. In the instrument, using a
synchronous detection system, the internal resistance is divided into impedance and
reactance, showing only the actual part.

if the resistance within the test line, the contact resistance between the object under test
and the test line or the contact resistance between the test line and the instrument
increases, then the instrument will be supplied to the abnormal current of the object
under test, which will cause the test state error, showing the "------" symbol where the
resistance is tested.
