II. Setting-up the Instrument
1. Working Environment
The location should be free from dust, moisture, chemical vapours and from mechanical vibrations.
Don't locate the instrument in bright or direct ambient light, in front of a lamp, or a will-lit bright wall. Best
image will be achieved without significant ambient light.
Environmental specification:
y Indoor use
y Altitude: Max 2000m
y Ambient temperature: 15°C~ 40°C;
y Maximum relative humidity: 75% for temperature up to 31°C decreasing linearly to 50% relative
humidity at 40°C
y Supply voltage fluctuations: Not to exceed ±10% of the normal voltage
y Pollution degree: 2 ( in according with IEC60664)
y Installation/Overvoltage category: 2 (in according with IEC60664)
y Air Pressure of 75kPa to 106 kPa
2. Input voltage and power
Automatic voltage selection works with electrical outlets worldwide. It is advised to always use a power
cord that is rated for the voltage used in your area and that has been approved to meet local safety
standards. Using the wrong power cord could cause fire or equipment damage.
In order to prevent electric fluctuation to the instrument electrics, always turn the power switch on the
instrument off before connecting the power cord.
This equipment must be used with UL60950-1 Listed power supply (E246759), MFR: LI TONG
ELECTRONICS CO., LTD. Model: LTE50E.S2.3.
y Input Voltage: 12VDC
y Input Power: 48W
y Power adaptor input rating: 100-240Vac, 47-63Hz, 1A
