GRAIGAR LZT-6200 User manual

PRODUCT OVERVIEW
LZT-6200 Microwave Radiation Detector is a new generation of electromagnetic radiation measurement
instruments Designed for measuring the electromagnetic radiation level of high frequency equipment.
Performance is more consistent, with very high sensitivity and accurate measurements as low as 0.1 μW/cm2.
Help users fully understand the level of the high-frequency electromagnetic radiation in the environment
around them thus allowing for health considerations.
FEATURES
• Simple operation, convenient measurement.
• Exceptional Value for money, easy to carry.
• Targeted measurement, high precision and high sensitivity.
• Well designed, professional appearance.
• Designed to comply with CE quality requirements.

INSTRUCTION MANUAL

OPERATION
1: Press the “POWER” switch, the display should show zeros but may not as there may be a EMF field in your
location. The instrument will display the strongest source in the Immediate area . The Built in sensor is located
in the top of the unit. Moving the unit about can minimize some interference.
❇❇
❇❇
❇Note: because of the environment and possible electromagnetic interference, the instrument can have non
zero reading, the instrument is not faulty.
2: While holding the instrument, move closer to the suspected source(s) of the electromagnetic radiation. The
unit will display the actual values of radiation from the equipment unless the value is less than the minimum
machine reading of 0.1 μW/cm2.
❇❇
❇❇
❇Note: In high Voltage or Power locations, Pay close attention to distance for exposure and safety.
3: “Data Hold” button is pressed, the top of the screen, above the numeric reading, displays “H” and the
displayed value is locked. Press “Data Hold” button again to resume testing.
4: “Max Hold” button is pressed, the top of the screen above the numeric reading, shows “MAX”. The instrument
will display a value that will only change when a higher peak is sensed. This function is used to detect maximum
field location in a specific environmental areal.
5: Low Battery symbol ( ) will appear at the top left of the display when the battery runs low. Please
replace the battery.
