Page 5: Push Button Functions
PUSH BUTTON FUNCTIONS Automatic dose rate and dose measurement Power on The meter is switched on by pressing the ON-button. Each time it is switched on the meter performs a self diagnostic routine, after which it automatically starts measuring both the radiation dose rate and the cumulative dose. -
Page 6: Additional Functions
Additional functions 3.2.1 Measurement mode selection In addition to the automatic mode there are two other user-selectable measurement modes available. The O-pushbutton is used to step through the modes (fast measurement - precision measurement - automatic measurement). Hold the O- pushbutton down for at least three seconds to switch from the current mode to the next mode in the cycle. -
Page 7: Alarm Tones
ALARM TONES The meter provides six different alarm tones. Only one of these can be emitted at a time. These alarm tones and their meanings are described below in order of importance: Meaning of tone Timing Duration 1. Battery voltage too low. - - - - - - - - - - - - - - - - 5 seconds ––... -

Indicates that the user-programmed alarm levels have changed and must be reprogrammed. The meter need not be returned for maintenance provided the fault does not recurr. USING THE DGM-1500 TURVA General The DGM-1500 is a versatile survey meter intended for measuring gamma- and X- radiation levels. -

paid to air conditioning filters, extractor fan filters, the base of roof gutter drainage pipes, car fenders and air filters etc. and other places where dust or rain water could collect. Dose measurement The DGM-1500 measures instantaneous dose rate and cumulative dose simultaneously. -
Page 10: Gamma Radiation Measurement In Foodstuffs
Gamma radiation measurement in foodstuffs The DGM-1500’s precision measurement function enables the measurement of extremely low dose rates, and therefore extends the area of application of the meter considerably. When a nuclear disaster occurs radioactive substances may be carried in the atmosphere for thousands of kilometres. - Page 11 Measurement of ambient level The ambient radiation level must be measured first. Note that when measuring the ambient radiation level the foodstuff sample should not be very close to the meter. The measurement is made for a periods of 1 or 2 or 3 hours. Press the O-button until the letter ‘h’...
- Page 12 Foodstuff measurement procedure briefly Measure the ambient radiation level in "h-mode" at least one hour (preferably three hours). Keep the foodstuff away from the proximity of the meter at this point. Press the O-button until "CS" is shown on the display. Then immediately place the foodstuff bag so that it is draped over the meter.

Page 13: About Radiation Units
About radiation units At the beginning of 1988 radiation units complying with the international SI-standard were adopted in Finland, and the Röntgen (R) replaced by the Sievert (Sv). The Röntgen/h is the unit of irradiation dose rate, and the dose is expressed in rem- units (Röntgen equivalent man). -
Page 14: Tests/Approvals
TESTS/APPROVALS The DGM-1500 Turva Personal Survey Meter is designed to operate reliably in environments prone electromagnetic interference. (Electromagnetic Compatibility) tests carried out by the Finnish State Research Center (VTT) show that the DGM-1500 operates without error in different kinds of magnetic field and when subjected to interference voltages entering via the mains adapter. -
