Step by step set up procedure for a correctly installed instrument:
Please consult the manual for placing and installing the instrument correctly.
Step 1: connecting the host box (HB) to power
After the HB has been connected to power, or following a time after any externally-initiated activity, the HB is asleep.
When it is asleep, the LED's entirely are extinguished.
Step 2: waking up the HB
Pressing either button on the HB will wake up the HB and display status.
The sensor was shipping in the locked state; therefore the HB will display the locked status (continuous RED) when
being installed for the first time after shipping.
Step 3: unlock the sensor
Press the LOCK/UNLOCK button and the sensor will be unlocked. This takes about 1s. The status LED (RED) will go
off and some or all of the three LED's indicating the sensor component's states (BLUE) go on.
Step 4: centering the sensor
Press the CENTER button. An autocenter will initiate. If successful, the status LED should be on (GREEN) and it's
ready to go. Unlike an STS-2, which may require several autocenter initiations, the STS-2.5 will typically accomplish
centering after one initiation.
Be patient, the centering process can take up to several minutes!
Step 5: It's operating
After ~60s the HB goes asleep again, all LED's go dark.
Be aware of the fact that the signal settling time after a perturbance (e.g. centering) is about 3 minutes. Temperature
equilibration after deployment may last hours and may cause apparent "offsets" on X, Y, and Z, which disappear when
temperatures are equilibrated and constant.
Step 6: prepare for shipping
To prepare for shipping, wake up the HB (if asleep), then press the lock/unlock button
until the RED status LED is steadily on. Power down and pack. Do not forget to cover the sensor connector with its
protection cap.
