Chapter 1: Introduction The Monitor 1000 is a health and safety instrument that is optimized to detect low levels of radiation. It measures gamma and x-ray radiation (ionizing radiation only). Its applications include: • Detecting and measuring surface contamination • Monitoring possible radiation exposure while working with radionuclides •...
Chapter 2: Features The Monitor 1000 measures gamma and x-ray radiation. It is optimized to detect small changes in radiation levels and to have high sensitivity to many common radionuclides. This chapter briefly describes The Monitor 1000 ’s features. The Monitor 1000 counts ionizing events and displays the results on the liquid crystal display (LCD).
The Buttons The Monitor 1000 has a circular membrane button on the face of the instrument, which consists of: Power (Enter), Alarm, Count, Audio (Minus), Menu, Backlight (Plus), and Mode. Power (Enter) Button The power (enter) button is located in the center of the membrane switch.
Mode Button The MODE BUTTON (Figure 2 (2)) is used to select from the available units of measurement. • mR/hr (MilliRoentgen) - displays the radiation level from .001 to 200. • CPS (Counts Per Second) - displays the radiation level from 0 to 3923. •...
Chapter 3: Operation Starting The Monitor 1000 Before starting the Monitor 1000 , install 2 AA alkaline batteries in the battery compartment located in the lower rear of the enclosure. You will need to remove the protective boot to gain access. CAUTION: Be sure not to press on the window of the GM tube while removing the boot.
Autoranging When radiation levels increase in some modes over certain preset levels, the Monitor 1000 uses autoranging, automatically changing from CPM to KCPM or from µR/hr to mR/hr. Operating in Dose/Rate Modes Caution: Be sure there is no obstruction between the detector window and the source being monitored/ surveyed.
Operating in Count Mode A timed count is useful for determining the average counts per minute over a longer period of time. The number of counts detected varies from minute to minute due to the random nature of radioactivity. When a count is taken over a longer period, the average count per minute is more accurate.
Menu Items Auto Averaging Turns auto averaging on or off. On by default. Data Logging Turns the internal memory on or off to record readings. Off by default. Set To Defaults Resets the Monitor 1000 to the default factory settings. Doing this will not change the deadtime and sensitivity, the time and date, or the data collection frequency.
Chapter 4: Common Procedures The following sections give instructions for several commonly-used procedures. With any procedure, the user must determine the suitability of the instrument or procedure for that application. Establishing the Background Count Normal background radiation levels vary at different locations, different times, even in different areas of the same room.
Chapter 5: Maintenance The Monitor 1000 requires regular calibration and careful handling to assure good measurements. Use the following guidelines to properly maintain the instrument. Calibration We recommend that the Monitor 1000 be calibrated annually, or as often as your regulations require. The best way to calibrate the Monitor 1000 is using a calibrated source at a calibration lab.
Chapter 6: Observer USB Software The Observer USB reads in Total Counts, CPM, µR/hr, mR/hr, CPS, µSv/hr, and has the ability to collect, log the data received, set the calibration date and settings, and echo the readings collected on a PC. The data is displayed on a graph, as well as a digital on-screen meter.
Observer USB Meter Screen The Observer USB Meter Screen (Figure 6(3)) simulates a digital meter to display the readings collected by the detector. Zero When the Zero is clicked, the averaging of the collected counts starts over. Averaging Time The Averaging Time selects the amount of time in which the previous readings are averaged.
View Preferences Use View > Preferences menu to adjust the settings in the Observer USB Preferences (Figure 6(5)). Chart Settings Autosave and Clear Chart Every Will automatically save and clear the chart at the number of minutes selected. Auto Save files are saved to the Observer USB Data folder located in the Documents Library.
Alarm cpm and Alarm Enabled To activate the alarm, enter the alarm threshold in the Alarm cpm field, and check Alarm Enabled. To disable the alarm, uncheck Alarm Enabled. If the alarm has been activated and Alarm Enabled is then unchecked, the alarm will continue to sound until Update Settings has been selected.
Chapter 7: Troubleshooting The Monitor 1000 is a highly reliable instrument. If it does not seem to be working properly, look through the following chart to see if you can identify the problem. Problem Possible Cause Action Display works, but no counts defective Geiger tube Replace it.
