Specifications
Number of Channels
Four (4).
Memory technology
EEProm; memory backup power not required, over 200 year data retention.
Inputs Accepted
All PACE sensors and probes, 0-5vdc, 2-wire resistance (30k
ohm midpoint), 3-wire potentiometer (>1k ohm), switch closure. Inputs
auto-configure for sensor or input range selected in software.
Sensors, probes and input signal types can be mixed in any
combination, except PM-1 Pulse Module which
is available on channel 4 only.
Additional input ranges
of +/-5vdc, 0-10vdc, 0-20vdc, 0-30vdc, 0-60vdc and 4-20ma are available
using the Input Scaling Module.
Additional input ranges of
+/-22mv and 0-50mv are available using a Thermocouple
/ Millvolt Module.
Starting Modes (3)
Start immediate, Start at pre-set time and date, Start on ch1 trigger*.
Recording Modes (3)
Record continuously, Record until memory is full, Record until ch1 stop
trigger*.
*If Channel 1 is set
for a temperature probe or a switch closure (using Pocket Logger Software),
the terminal block can be plugged in to start and/or unplugged to end
a logging session (a switch closure can do the same). Ch1 may be set to
'OFF' to maximize memory capacity of 'ON' channels.
Sampling Rates (20)
2, 4, 6, 10, 20, 30 seconds; 1, 2, 5, 10, 15, 20, 30 minutes; 1, 2, 3, 4,
6, 8, 12 hours. Timing accuracy: ± 2 min. / month for 10 sec.
- 12 hr. rates; Timing accuracy for 2, 4, & 6 sec. rates
is ±30% if memory is in wrap-around mode, otherwise accuracy is ±
2 min. / month.
Fast Sampling Rates(8)
200/sec, 100/sec, 50/sec, 20/sec, 10/sec, 5/sec, 2/sec, 1/sec. Note:
While recording at fast sampling rates, communication with a PC is not
available until logging has stopped. Timing accuracy: ±
0.5%.
Sampling Modes (3)
Single Point, Average (accumulate readings every 2 seconds; compute and
store average value at preset sample time), Pulse Counting (channel 4
only, requires PM-1 Pulse Module).
Text blocks (5)
The Pocket Logger accepts custom labels for each channel and the logging
session. These labels display on the status screen, real time screen,
all created graphs and ASCII files.
Real Time Display Mode
Pocket Logger input channel values (in engineering units) are updated
every 2 seconds (while connected to a PC running Pocket Logger Software).
Real Time Display Mode does not affect any ongoing logging session.
Real Time Clock
Counts seconds, minutes, hours, day of week, month, date of month, and
year with leap year compensation.
Clock accuracy: Better than +/- 2 min. per month at 25°C.
Battery
Replaceable 9 volt lithium battery. Battery life: Estimated 2 - 3 years.
A standard 9 volt alkaline battery can also be used (est. life: 15 months).
Actual battery voltage displays on PC (when logger is connected to a PC
running Pocket Logger Software).
Enclosure
Impact-resistant ABS plastic case.
Size
4.70" by 2.40" by .95"
120 mm x 61 mm x 24 mm.
Weight
6 ounces; 156 grams (includes battery).
Operating ambient temperature
range
-40°C to 60°C. (-40°F to 140°F).
Operating ambient humidity
range
0 to 90% relative humidity (non-condensing).
Communication
Serial RS232C. Baud Rates: 1200, 2400, 4800, 9600 and 19.2k baud. Data
and status transfers to PC (and real time display mode) do not affect
any ongoing logging session.
Interface Cable
Terminations: 9 pin D-Sub female (connects to PC); 3.5mm stereo phone
plug (connects to Pocket Logger). Length: 6 feet; 1.8 meters. (Part No.
IC209)
Recommended sensor cable
Two, three, or four conductor, 22 - 24 gage, stranded copper.
Maximum resistive probe
cable length
Using 24 gage shielded cable: 500 feet (150 meters). Greater cable lengths
are possible using heavier gage cable.
Input connection
Removable screw-type terminal block.
Input impedance
Greater than 5 megohms (while sampling).
Input protection
Over/under voltage protection on all inputs: 40 amps peak 8/20 microseconds.
Approvals
CE approved to EN50081-1 (RF emissions) and EN50082-1 (ESD
and RF immunity) using any combination of CE approved PACE sensors or
probes with standard lead lengths. All PACE Sensors and Probes are CE
approved except the following: PACE SC series AC Current Sensors, PACE
SV series AC Voltage Sensors.
Calibration
Not required; Accuracy specifications are maintained without user adjustment.
Contains no adjustable components. An NIST traceable Validation Certificate
is included with each Pocket Logger. An accuracy validation procedure
is included in the Pocket Logger Software's
online help.
Pulse Counting (using
PM-1 Pulse Module):
Maximum Rate: 5 pulses per second
Minimum Closure: 30 milliseconds
Maximum Pulses (see below)
Resolution dependent
specifications
The XR440 can be set to 12,
10 or 8 bit resolution. Selecting a lower resolution increases the number
of readings which can be stored in the XR440's memory.
