Page 12: Warning Instructions
Warning instructions Warning General instructions governing the use of field strength measuring equipment Do not touch or use the field strength meter to touch items carrying dangerous voltages. Make sure that you know which laws, standards and regulations apply in your area. - Page 13 Warning instructions Never place or hold field strength measuring equipment inside field generating equipment or machines (e.g. microwave ovens or induction furnaces) as this may result in destruction of the field strength measuring equipment which is not designed to withstand field strengths intended for materials processing.
- Page 14 Warning instructions Warning The safety of persons within electromagnetic fields must not be based purely on the measured values produced by field strength measuring equipment, since the built-in redundancy is not sufficient to ensure that the instruments will always function correctly at all times. ...
- Page 15 Warning instructions Be advised that field strength can be attenuated by wet clothing. ESM “RadMan” should be worn outside the clothing to exclude the possibility of underestimating the electromagnetic field strength. Be advised that any kind of sticker or metallic label in the sensor area may lead to underestimated electromagnetic field strengths.
- Page 16 Warning instructions Warning Strong, low-frequency electrical fields, for instance in the vicinity of high-voltage cables, may sometimes influence the displayed value, especially when the ESM “RadMan” is used as a rapid tester or as a leak locator.

Page 29: Applications And Use
Applications and use Areas of use ESM “RadMan” has the following main areas of use. As a warning unit As a rapid tester As a leak locator ESM-30 only: Data recorder General handling instructions Moving the instrument rapidly in an electrostatic field can have a disruptive influence. - Page 30 Applications and use Using ESM as a personal warning unit Application The ESM “RadMan” is worn on the body, preferably by placing it in the breast pocket of your shirt or jacket. Preparation Slide the yellow absorber cap over the end of the instrument.
- Page 31 Applications and use Procedure Stand in your normal working position and slowly turn around through a complete circle. This allows ESM “RadMan” to better detect radiation sources that are behind your back when you are working normally. If the alarm sounds, leave the danger area carefully and without panic.
- Page 32 Preparation Slide the yellow absorber cap over the battery compartment. The “narda” marking is no longer visible. Field reflections caused by the human body are no longer screened. The clip should point to the LED side. If required: Screw the extension rod on to the absorber cap.
- Page 33 Applications and use Procedure Check your environment for sources of electromagnetic radiation. If required: Screw the extension rod on to the absorber cap. After the check, screw the ESM “RadMan” to a non-metallic tripod so that you can work in the area and still be warned of any dangerous electromagnetic radiation levels.
- Page 34 The ESM “RadMan” is used to detect leaks in waveguides. Preparation Slide the yellow absorber cap over the battery compartment. The “narda” marking is no longer visible. The clip should point to the LED side. If required: Screw the extension rod on to the absorber cap.
- Page 35 Applications and use Procedure Hold the ESM “RadMan” at arm’s length. Move the ESM “RadMan” slowly along the waveguide at a relatively large distance from it. If a leak is suspected, slowly move the ESM “RadMan” closer to the suspected location.
- Page 36 Applications and use Using ESM-30 as a data recorder Applications The data recorder records the variation with time of the surrounding electromagnetic radiation. If ESM-30 “RadMan XT” is worn as a warning unit, the exposure of the wearer during the course of the working day can be recorded.
- Page 37 Applications and use Connecting the earphone The earphone supplied can be connected to the ESM “RadMan” so that the audible alarm can still be heard reliably even in areas where high noise levels are present.
- Page 38 Applications and use Reading out measured values The measured values can be read out via the optical interface (A) of the ESM “RadMan”. Data is transferred at a rate of 25 measured values per second. The E-field and H-field values are output separately with much higher accuracy than the LED display.
- Page 39 Applications and use The ESM-TS Interface Set is required to read out the measured values from the ESM “RadMan”. It includes software, a fiber optic cable, and an opto/electric converter with USB connector. The software program allows a wide range of remote control functions and also allows measured values to be read out and saved.

Page 41: Checking Field Probe Function
Checking field probe function Checking the function The sensor functions of the ESM “RadMan” can be checked with the aid of a Test Generator (BN 2244/90.38). The H-field and E-field sensors are tested separately. 1. Place the Test Generator in the vicinity of the sensors. - Page 42 Checking field probe function Tip: Make sure that the Test generator batteries are not run down, otherwise the output power of the generator will be insufficient to properly test the field sensors. Although performing an extended self-test with the aid of the Test Generator may permit a fault to be detected, it provides no guarantee that all sensors are measuring correctly, for instance after inexpert handling such as when...
