It will be shown upon switching on the NFA and when logging (see chapter 5.4). Due to the increased power consumption (LEDs, sound signal, etc), the remaining battery life in the operating mode “ON” is reduced by up to 30%. - 6 - 350-027_NFA1000-6-0_EN as of August 2011 © Gigahertz Solutions GmbH... - Page 7 The LED’s for 16.7 Hz, mains frequency and its harmon- ics up to 2 kHz have a suitable lock-in range to cover mains fluctuations. - 7 - © Gigahertz Solutions GmbH 350-027_NFA1000-6-0_EN as of August 2011...

If closer, your presence can influence the measurements. - 9 - © Gigahertz Solutions GmbH 350-027_NFA1000-6-0_EN as of August 2011... - Page 10 For other measuring ranges just compare the position of the comma and convert accordingly. Readings below 0.1µW/m² cannot be displayed or recorded because of noise-issues. - 10 - 350-027_NFA1000-6-0_EN as of August 2011 © Gigahertz Solutions GmbH...

The meter turns off after quarter of an hour NFAsoft allows you to change the interval for the auto-power- off feature. (Auto-power-off is deactivated while recording!) - 28 - 350-027_NFA1000-6-0_EN as of August 2011 © Gigahertz Solutions GmbH... - Page 29 Therefore you cannot use NFAsoft to check the con- figuration of the NFA, but only to instal new configurations.
