We recommend the logger be recalibrated every year. You may recalibrate the logger longer
than a year depending on your application standard.
You may return the logger to the supplier for recalibration service or recalibrate it on your own
via SiteView software.
SiteView software provides two-point calibration for the most of the loggers.
1.7 Safety Warning
Maximum Input Voltage Range
For logger model: iVDC-10, iTC-80:
The logger is designed to measure single common ground DC voltages in the range up to 10
VDC. Any voltages over this range may cause permanent damage to the device.
For logger model: iBG-[X]:
The logger is designed to measure strain gauge/bridge signal up to ±520mVDC. Any
voltages over this range may cause permanent damage to the device.
Maximum Input Current Range
For logger model: iCDC-25:
The logger is designed to measure single common ground DC current in the range up to 25
mA. Any current over this range may cause permanent damage to the device.
External Power Supply
When using external power supply (via USB, Serial Port, Device Server, or thirty party +5
VDC power supply) to power the logger please make sure that the external power supply has
the same common ground with the external input process signals.
When using other third party external power supplies, please make sure the voltage of the
external power supply is +5 VDC (+/- 5% ripple).
Grounding
The common ground of the iLog data logger is connected directly to the ground of the input
process signals and the ground of the external power supply (if applicable).
