Other Functional Specifications
• Status display
Configuration mode, data transmission, and battery
status are indicated with LEDs (green and red).
(Indication can be turned off.)

Low battery warning Green lit (0.1 seconds), all off
(1.9 seconds)
Red lit (0.1 seconds), all off (1.9
seconds)
The above sequence is repeated
twice, and then the LEDs are off
for 10 seconds.
Input error Off Lit for 0.1
seconds at
about 5 second
intervals
Mode setting error * Repeats the sequence of green
and red lit in sync (0.1 seconds)
and all off (0.9 seconds) three
times, turns off for 2 seconds,
and repeats the entire sequence.
* For example, configuring in a mode other than measurement
mode when there is no USB connection.
• Self-diagnosis function
Transmits the following device status to the
coordinator
• Low battery warning: Low battery voltage detected.
• Critical low battery warning: Minimum drive voltage
detected. Batteries must be replaced quickly.
• Input error:
Calibration value error
A/D error
Hardware error
Memory error
Process error
• Wireless communication error: Configuration
mismatch, ambient radio environment detection
• Firmware upload
Firmware can be updated using the Wireless Input
Unit Configurator.
• Operation mode
Change between measurement and configuration
mode with a switch.
• Wireless function*
The wireless function can be turned on and off with a
switch.
* When using the GX70SM as a standalone data
logger, you can turn off the wireless function to
prolong the battery life.
• Data logging function
Saves up to 4500 data points per channel.
