Overview
The USB-5200 Series provides temperature measurement flexibility and conveniencein devices that can be moved and installed anywhere temperature measurements
are needed, without the need for a dedicated host computer. The USB-5200 Series
offers the most accurate temperature measurement possible, since the internalmeasurement electronics accuracy exceeds the accuracy specifications of thetemperature sensors.
The combination of the USB-5200 Series and the Measurement Computing DAQ
software suite gives you a complete data acquisition solution that will have you
taking measurements in minutes.

Temperature Input
The USB-5200 Series provide eight temperature input channels.
The USB-5201 is programmable for different thermocouple types. The USB-5203 is
programmable for different sensor categories, including thermocouple, RTDs,
thermistors and Semiconductor sensors.

A 24-bit analog-to-digital (A/D) converter
is provided for each pair of analog inputs.
Users can connect a different category of
sensor to each temperature channel pair.
Open thermocouple detection (OTD) is
provided to detect broken thermocouples.
Cold junction compensation (CJC) sensors are provided for TC measurements,
and built-in current excitation sources forresistive sensor measurements.

Stand-Alone Logging
to CF Card

1

Each channel can be sampled at up to
two samples per second for a total device
throughput of 16 samples per second.

Digital I/O
Eight independent digital I/O lines are
independently configurable for input
or output, and can be used to monitor
TTL‑level inputs, communicate withexternal devices, and generate alarms.

Data Logging
USB-5200 Series devices store temperature
data on a Compact Flash (CF) card. The
data can be read from a CF reader or byconnecting the device directly to a USB
port on a PC. External power is requiredfor data logging operations.
Users can configure the device to log
temperature (°C) or raw data, timestampdata, and CJC sensor readings. All logging
options are configurable with software.
Logged data is stored on the memory card in binary files and can betransferred to the computer. Use
InstaCal to convert the files to .csv or.txt format for use in other applications.

Calculating the Logging Time for a Memory Card

For example, if logging from one channel to a 512 MB cardwith all logging options selected, the calculation is as follows:

The following formula calculates the approximate amount oflogging time in seconds that a supported memory cards allows.
USB-5200 Series supports 512 MB, 1 GB, and 2 GB CompactFlashmemory cards.

time = R ×

where:NDisk
NTS + NDIO + (NTemp × nChannels) + NCJC•

NDisk = 512,000,000 bytes (512 MB)•

NDIO = 1•

nChannels = 1•

R = 1 S/s•

NTS = 6 (timestamp enabled)•

NTemp = 4 (temperature readings)
NCJC = 8 (CJC sensor readings enabled)•time = total disk time in seconds••

NDisk = size of memory card in bytes•

NDIO = 1 byte for digital I/O

Inserting these values into the formula creates the following
equation:•nChannels = number of channels logged•

R = logging rate in seconds•

NTS = 6 bytes for timestamp, if enabled•

NTemp = 4 bytes for a temperature reading (always
enabled)•NCJC = 8 bytes if CJC sensor readings are enabled

Measurement Computing(508) 946-5100

512,000,000= 26947368 seconds = 311.9 days
6 + 1 + (4 × 1) + 8
Changing the number of channels logged from 1 to 8 in theabove formula (nChannels = 8) yields the following equation:
time = 1 ×time = 1 ×

2

512,000,000
6 + 1 + (4 × 8) + 8= 10893617 seconds = 126 days

the time is = or > the specified time, at which time the LED turns on. First sample
acquired 1 second after the LED turns on unless <5 seconds since power on.

Stop on button press: hold down the button until the LED turns off. The device
caches logged data in volatile memory prior to writing to memory card.
Logging status indication: The LED operations when connected to the AC power
adapter are different than when connected to USB.
Logging off: The LED is off (disabled).
Start logging on power up: LED turns on, blinks when data is captured.
Start logging on button: The LED is initially off. When the button is pressedand held for approximately 1 second, the LED turns on and acts the same as
Start Logging on Power Up mode.
Start logging at specified time: the LED turns off, with a momentary on flash
every second. When the specified date/time is reached, the LED turns on.
Other indication: Press and hold until LED is off to stop logging and store
remaining data. LED blinks when the card is full or removed when logging.
