Appendix C – MicroDataLogger® Specifications
Channel Capacity
Four universal input/output channels
accept both analog and digital signal
conditioning modules.
Module Auto ID
Automatic logger programming of
module/sensor signal type and range
information.
Analog Resolution
1.2 mV or 4,096 parts (12 bit A/D
conversion).
Analog Accuracy
±0.1% of full scale reading based
on a precision voltage reference (3
ppm/°C typical temperature
coefficient).
Real-Time Clock
±1 minute/month over full operating
temperature range.
Sample Interval
User-programmable sample
intervals: 3, 6, 15, and 30 seconds
and 1, 2, 3, 5, 10, 15, 20, 30, and 60
minutes.
Enclosure
Injection molded, gray ABS plastic,
standard: environmentally sealed;
NEMA-12, or 4X optional.
Mounting
Two through-holes each for #6-32
flat-head screws standard; magnetic,
Velcro and other types of mounting
optional.
Size and Weight
14.7 x 12.6 x 5.7 mm (6 x 5 x 2.25
inches) and 500 g (17.6 oz.)
including internal battery and with no
modules installed.
User Interface
16 characters by two line alpha-
numeric display, push-button switch
and audible signal tone.
User Interface
16 characters by two line alpha-
numeric display, push-button switch
and audible signal tone.
Computer Interface
RS-232 serial interface; baud rate:
default 19,200 bps; data format:
eight data bits, no parity, one stop
bit; cable 72 in. (183 cm) with nine-
pin female “D” type connector.
Memory Capacity
64,000 measurements total (i.e.
16,000 per channel).
Memory Retention
Data retention greater than 20 years
without power, using non-volatile 128
kbytes Flash memory chip.
Internal Power
Six volt, one Ahr., rechargeable
sealed lead-acid battery pack.
Typical recharge time is 8 to 12
hours.
Environmental
Operating: +32 to +122 °F (0 to
+50°C), 90% RH non-condensing.
Storage: -4 to +140 °F (-20 to
+60°C), 5% to 95% RH non-
condensing.
FCC Compliance
Class B, sub-part J, paragraph 15,
and European standard CISPR 22
Battery Life
When taking readings once per
minute using low-power sensors,
battery is 30 days or more. Less
frequent sampling results in
longer battery life. A fully-
charged battery will power a
typically configured logger for a
minimum of 70,000 logged
readings.
