CATⅠSecondary electrical circuits that are connected
to a wall outlet through a transformer or similar
device.
CATⅡPrimary electrical circuits in equipment
connected to a wall outlet via a power cord
(portable tools, household appliances, etc.)
CATⅢPrimary electrical circuits of heavy equipment

Measurement categories (Overvoltage categories)
This product complies with CAT I safety requirements.
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.
Higher-numbered categories correspond to electrical environments
with greater momentary energy. So a measurement device
designed for CAT III environments can endure greater momentary
energythanadevicedesignedforCATII.
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.

Notes on Use
______________________________________________________________
WARNING
The maximum input voltage is 45 V DC. Attempting
to measure voltage in excess of the maximum input
could destroy the product and result in personal
injure or death.
To avoid electric shock, do not allow the product to
get wet, and do not use it when your hands are wet.
CAUTION 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.
Before using the product, make sure that the insulation on
the cables is undamaged and that no bare conductors are
improperly exposed. Using the product in such conditions
could cause an electric shock. Replace the test leads and
probes with the specified Hioki Model 9629 or 9632.
To avoid damaging the product, do not drop it or subject it
to intense shock.
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.
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.
If the protective functions of the product are damaged,
either remove it from service or mark it clearly so that
others do not use it inadvertently.
Adjustments and repairs should be made only by
technically qualified personnel.
Use only the specified connection cable. Using a
non-specified cable may result in incorrect
measurements due to poor connection or other
reasons.
Notes on Use
Follow these precautions to ensure safe operation and to
obtain the full benefits of the various functions.

Product Outline
The 3639-20 PULSE LOGGER counts and records the
pulses of pulse signals (mechanical contact inputs of
switches, relays, etc., or voltage inputs from 1.5 V to 45 V)
at a specified interval. It can be used for a wide variety of
devices that deliver pulse signals, such as rain gauges, flow
meters, and the like. As data is stored in a nonvolatile
memory, it is not lost even if the batteries run out or are
removed for replacement.

1.3 Battery Life
The service life of the batteries used in the 3639-20 varies
depending on the recording interval, power save function
setting, measurement-value display during recording,
temperature and humidity, and the like. The table below
gives the approximate battery service lives with an average
pulse count of 5 or less per second, and at 23 5 .

WARNING
To avoid electric shock when replacing the batteries,
first disconnect the connection cable from the object to
be measured.
During battery replacement, use caution not to put any
foreign materials such as a metal object into the
product to avoid damage to the product.
Before using the product after replacing the batteries,
replace the cover and screw.
Do not mix old and new batteries, or different types of
batteries. Also, be careful to observe battery polarity
during installation. Otherwise, poor performance or
damage from battery leakage could result.
Handle and dispose of batteries in accordance with
local regulations.
CAUTION When exchanging the batteries, the circuit may sometimes
short circuit due to static electricity. As far as possible, do not
touch the base board with bare hands.
Chapter 2
Set Up
2.1 Replacing the Battery
The installation of new batteries ensures more than six
months of recording (with the Power Save function turned
ON, the recording interval set to 10 seconds or longer, no-
voltage contact input with an average pulse count of 5 or
less per second, and at 23 5 .

2.2 Power Save Function
If no recording session is under way, the screen display is
automatically turned off approximately 15 seconds after the
last key entry (Sleep). However, the recording-interval setup
screen will not enter the Sleep state, even in the absence of
key operation.
The Power Save function mode is set to ON in the initial
settings. If the Power Save function is disabled, the battery
service life will be approximately 15 days. For the setting
procedure for the Power Save function, refer to the "3911-
20 COMMUNICATION BASE Instruction Manual" and the
Measurement Guide.
When the Power Save function is set to ON (enabled)
before measurement starts, the measurement-value display
turns off 15 seconds after measurement starts, and the unit
automatically enters the Power Save function. To turn on
the measurement-value display again, press any key. The
measurement-value display turns on, then turns off after 15
seconds, and the unit automatically enters the Power Save
function again.
When the Power Save function is set to OFF (disabled)
before measurement starts, pressing the INTERVAL button
turns the Power Save function ON/OFF. When the
measurement-value display is on, the Power Save function
is set to OFF. When the measurement-value display is off,
the Power Save function is set to ON. For an extended
measurement operation, set the Power Save function to ON
(measurement-value display turned off).

2.4 Connecting Sensor Cable
Connecting the CONNECTION CABLE
The 3639-20 PULSE LOGGER is capable of measuring one
channel of pulse signals with the 9629 CONNECTION
CABLE connected. To ensure correct measurement, insert
the CONNECTION CABLE as far as it will go.
The 9629 CONNECTION CABLE can be cut to any
desired length for use. If the cable was cut, use it after
stripping the covering with a wire stripper or another
appropriate tool.
To input a voltage to the 3639-20, connect the red
conductor to the positive (+) side of the pulse-generating
device, and connect the black conductor to the negative (-)
side. If the conductors are inversely connected,
measurement cannot be conducted.
