DANGE
R
To prevent the danger of electric shock or damage
to the unit, never input more than 450 V(either AC
or DC) between a pair of analog input units or
between an analog input unit and the main unit.
To prevent damage to the 8804, never exceed the
limits in the following table for the various input
connections.

Analog input 500 V DC＋AC peak
EXT TRIG -5 V to ＋10 V
TRIG OUT -20 V to +30 V 500 mA max

When using an AC adapter, always use the
specified 9418-10 AC ADAPTER(PSA-30U-120,
PHIHONG). The rated supply voltage is 100 to 240
VAC. (Voltage fluctuations of 10% from the rated
supply voltage are taken into account.) The rated
supply frequency is 50/60 Hz. Do not use a power
supply that falls outside of this range.
N
otes on Use
In order to ensure safe operation and to obtain maximum
performance from the unit, observe the cautions listed
below.

―――――――――――――――――――――――――――――――――――――――
Notes on Use
―――――――――――――――――――――――――――――――――――
WARNIN
G
When using the batteries, use LR6 alkaline batteries
or 9420 BATTERY PACK. In this case, do not use
new batteries with old ones. Also, do not mix
batteries of different types. We take no
responsibility for an accident using the batteries
and battery packs which are not specified.
When using the 9420, always use 3 pairs of cells
together. Do not use different types of batteries.
CAUTIO
N
･The logic inputs are not floating. Although two sets of
logic probes can be connected, they all have a common
ground with the main unit.
･To avoid damage to the unit, do not input a
voltage/current exceeding the rated maximum to the
external input terminals.
･The optimal operating temperature and humidity range
of the unit is 5℃to 40℃and 35% to 80% RH or less.
Do not use the unit in direct sunlight, dusty conditions,
or in the presence of corrosive gases.
NOTE
(1) Before Powering On
・Check that the correct 9418-10（PSA-30U-120,
PHIHONG), 9420, or LR6 alkaline batteries are fitted.
・Be sure to connect the protective ground terminal to
ground. Connect the protective ground terminal to a
grounding conductor before making any other connections.
・When using an AC adapter and if properly grounded
three-pin outlet is available, then using the three-core
power cord provides automatic grounding.

Notes on Use
―――――――――――――――――――――――――――――――――――
(2) Using the Printer
・Using the printer for low-speed printing (Recorder
function) in a high temperature or high humidity
environment should be avoided at all costs. This can
seriously reduce the printer life.
・If the recording paper is mistakenly inserted back to
front, waveform recording is impossible.
(3) Recording Paper
・This unit uses a thermal printer. The recording paper
supplied has characteristics finely tuned for use with the
printer.
・Using recording paper of a different specification may not
only result in impaired printing quality, but even prevent
the printer from operating. Always use the 9232
RECORDING PAPER.
(4) Storage
If the unit will not be used for a substantial period, to
protect the printer head and prevent deformation of the
rubber rollers, move the head up/down lever to the head
up position. If the unit is left in the state in which the
head is applying pressure to the platen roller, the roller
may be deformed, and the printing may become uneven.
(5) Shipment
If reshipping the unit, ensure that the recording head is
in the up position and preferably use the original packing.
