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 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 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.

1.2 Features
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.

Measurement Preparations

For the procedure of attaching the 8992 PRINTER UNIT and the 8993 DIGITAL I/O UNIT, see Section 11.1.1 "Connecting the 8992 PRINTER UNIT" (page 181) and Section 12.1 "Connecting the 8993 DIGITAL I/O UNIT" (page 198).
2.1 Connecting Power

2.1.1 Connecting the AC Adapter

• Turn the instrument off before connecting the A C adapter to the instrument and to AC power.
• Use only the supplied 9418-15 AC ADAPTER (SA145A­1240V-6, SINO AMERICAN). AC adapter input voltage range is 100 to 240 VAC (with ±10% stability) at 50/60 Hz. To avoid electrical hazards and damage to the instrument, do not apply voltage outside of this range.

2.1 Connecting Power
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
205.)
See Section 7.3.6 "PC Card Initialization" (page 128.)
• 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.
Page 35

2.1.2 Installing the Battery Pack

For battery operation, use only the 9447 BATTERY PACK. We cannot accept responsibility for accidents or damag e related to the use of any other batte ries.
23
2.1 Connecting Power

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.
See Section 16.6 "9447 BATTERY PACK Charging" (page 256.)
Turn off the power switch.
1.
Remove the battery compartment.
2.
Insert the 9447 BATTERY PACK until

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.

4.7 Setting the Digital Filte r

4.7 Setting the Digital Filter
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.

5.2.2 Measuring 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.
t[s] totalized pulses - (t-1) [s] totalized pulses
Pulses per rotation
for t = 2s is calculated as follows:
t=2

2000 - 1000

5.4.1 Analog Channel Scaling

• The scaling function converts the voltage from a sensor to physi­cal units that correspond to the measured quantity.
• The gauge, vertical axis limits and A-B cursor values can be dis­played as scaled values and units.
Setting by Conversion Ratio
Scaling can be set by entering the physical quantity per volt (con­version ratio = eu/V) of input signal, and the offset and name of units (eu = engineering units).
