Page 17
Measurement Categories (Overvoltage categories)
This instrument complies with CAT I 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.
5
1
CAT ISecondary electrical circuits connected to an AC
electrical outlet through a transformer or similar
device.
CAT IIPrimary electrical circuits in equipment connected to
an AC electrical outlet by a power cord (portable
tools, household appliances, etc.)
CAT IIIPrimary electrical circuits of heavy equipment (fixed
installations) connected directly to the distribution
panel, and feeders from the distribution panel to outlets.
CAT IVThe 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.

1.2Features
Compact & Lightweight
The lightweight, B5-size (182 x 257 mm/ 7.17" x 10.12") portability
of these instruments makes them ideal for use where space is limited, and the dual-power (AC adapter or battery) capability makes
them ideal for mobile applications as well.
Isolated Input Circuits (Analog & Pulse)
Analog and pulse channels can be recorded in combination. The
input circuits are fully isolated, so they can be safely connected to
points of independent potential.
Digital Filter
This instrument has a built-in delta-sigma AD converter, which
offers a high level of noise reduction. The longer the recording
interval is, the larger the noise reduction effect becomes; this
ensures highly accurate measurement with little scatter.
High-Resolution (16-bit) Ana lo g Inputs
The eight analog channels in the 8420-51 (16 in the 8421-51, 32 in
the 8422-51) measure up to 60 VDC, temperature with nine types
of thermocouples and two types of resistance temperature detectors*, and humidity* with an optional sensor. Both three- and fourwire resistance temperature detectors are supported. The input terminal block can be easily removed to facilitate connections in difficult cond i t io n s .
* 8420-51, 8421-51 only
100 ms Recording Intervals*
The shortest recording interval is 100 ms, during which data at all
input channels can be scanned. The recording interval can be set
in 16 steps from 100 ms to one hour.
* 8420-51, 8421-51: The recording interval is five seconds or
longer when one or more channels are set to humidity measurement.
8422-51: The recording interval is 200 ms or longer when the
channels between CH17 and CH32 are used.
Four (16-bit) Pulse Input Channels
Four pulse-input channels are provided for totalization and rotation
rate measurements. Rotations are measured by counting pulses
from an encoder. Flow and power can be measured simultaneously with temperature by flowmeter and wattmeter pulse measurements.

Make sure the instrument is OFF.
1.
Connect the AC adapter to the instrument.
2.
Plug the AC adapter into the power outlet.
3.
• Make sure the power is turned off before connecting or disconnecting the AC adapter.
• Data can be retained for about ten minutes after power is interrupted. Operation after power interruption depends on the setting for Resume Recording After Power Loss.
See Section 13.1.2 "Setting the Start Backup After Power Loss" (page
• Having the 9447 BATTERY PACK installed can help protect
against power interruption. When the AC adapter and a battery
pack are both installed, the AC adapter takes priority.
• This instrument will not run erratically under a momentary
power outage lasting less than 40 ms. However, if a momentary outage of 40 ms or more occurs, the instrument turns off
temporarily, so the power condition at the installation location
should be considered beforehand. Therefore, consider the
power supply conditions at your installation site before installing the instrument.

The battery pack is subject to self-discharge. Be sure to charge the
battery before initial use. If the battery capacity remains very low
after correct recharging, the useful battery life is at an end.
Continuous Operating Time with the 9447 BATTERY
PACK
(at 23°C and unused printer.)
• Voltage measurement
• Backlight saver enabled (5 min)
• After 10 h (approx.) charging
• Voltage measurement
• Backlight brightness
• After 2.5 h (approx.) charging
The times in this table depend on ambient temperature.
• Continuous operating time is about doubled when a second
battery pack is installed in the 8993 DIGITAL I/O UNIT.
• When operating from a battery pack, the instrument au tomatically turns off as the battery becomes discharged. If the instrument is allowed to remain in this state for a long time, the
battery pack can become overdischarged, so the power switch
should always be turned off.
• The battery pack is subject to self-discharge. If stored or otherwise not used for a long time, the battery pack should be discharged and then recharged at least once every two months.
Battery capacity may be degraded if stored for a long time
without charging.
• For long-term storage, remove the battery pack from the instrument.
• The battery pack is a consumable. If the battery capacity
remains very low after correct recharging, the useful battery life
is at an end.
• The life of the battery pack is 500 charges or one year, whichever comes first.
• Printing with the battery pack may result in light printouts. We
therefore recommend that the AC adapter be used when printing.

A digital filter can be used on analog channels to remove noise in
the input signals.
The longer the recording interval is, the larger the noise reduction
effect becomes; this ensures highly accurate measurement with little scatter.
❖See "Recording Interval and Cutoff Frequency table" (page 238.)
For example, assuming that channels CH1 to CH16 are used, and
the digital filter is set to 60Hz, noise reduction in the supply frequency is maximized at a recording interval from 2 sec. to 1 hr.

5.2.2Measuring Rotation Rate
79
Rotation is measured by counting pulses output from a device such
as a rotary encoder or rotor. Input pulses are totalized over a onesecond period to determine the rotation rate.
The rotation rate scaling function can be used to convert totalized
rotation pulse counts to physical units.
❖ See Section 5.4.3 "Pulse Channel (Rotation) Scaling" (page 94.)
Rotation Rate Measurement Theory
When rotation rate measurement is selected, pulses are internally
totalized every 100 ms.
Totalized Pulses
The rotation rate at time t[s] is calculated by dividing the number of
pulses from (t-1) to t[s] by the number of pulses per rotation:
r =
[rps]
Example: Pulses per rotation = 4
After 1s, totalized pulses P10 = 1000 counts
After 2s, totalized pulses P20 = 2000 counts
In this case, the rotation rate r
r
t=2
If time t[s] < 1 second
The totalized pulse value of t-1[s] is not measurable, so the value
that is ten times the totalized pulses between t-0.1[s] and t[s] is calculated as the totalized pulse value between 1s, so the rotation
rate can be calculated. For this reason, the rotation rate when t is
less than one second may vary.
