Receiving Inspection

Upon receipt of the Survey Meter:

1. Check the shipping cartons(s) and their contents for in-shipment damage.

2. Check that all items listed on the packing slip are present and in good

condition.

If damage is evident, make a claim with the carrier and contact Fluke

immediately. If items are missing, contact Fluke. See How to Contact Fluke.

Operation

The following sections describe the operation of the Survey Meter.

 Warning

To prevent possible electrical shock, fire, or personal injury:

• Do not put metal objects into connectors.

• Fluke recommends that you wait for a one-minute warm-up

period before you make a measurement. If the Survey Meter

experiences a very large temperature change (for example,

it moves indoors from outside) a longer warm-up period can

be necessary to measure a value less than 50 μR/h.

External Controls

There are two external controls on the Survey Meter: and ON/OFF button and a

MODE button.

ON/OFF Button

Press the ON/OFF button to turn on the Survey Meter. All the elements in the

display turn on and the microprocessor runs through an initialization procedure.

Part of the procedure includes reading the calibration coefficients stored in

EEPROM. If an EEPROM read error occurs, an error code (E1) displays at

power-on and unity calibration coefficients are used.

The bar graph and digital display will show a reading that decreases as the

Survey Meter stabilizes. The initial reading usually starts in the 5 R/h range and

decreases through the lower ranges to a reading of less than 50 μR/h within

120 seconds. When the elements in the display turn off, with the exception of

those necessary for normal operation, the user can begin the measurement

process.

Note

Background fluctuations may occur (less than 50

R/h) returning to

original reading typically in less than 3 seconds.
