Additional Environmental and Performance Parameters of Smart Fieldmeter

Questions:

1. What is the temperature operation range?

2. What is the humidity operation range?

3. What is the resolution?

4. What is the overload field?

Answers:

1. Temperature range of this meter we tested is 0 C - 50 C. The associated thermal error with respect to calibration temperature of 24 C depends on the range but is less than 0.08 dB/C.

2. Humidity RH operating range for the whole system is 5% - 90%, non-condensing. The probe and meter are “splash proof”.

Probe is sealed by design. On request we may supply an environmentally enhanced variant of the probe (not meter) operating at RH=100%, condensing.

3. Resolution is defined by the display. Maximum resolution is:

0.01 V/m (ranges 2 V/m, and 20 V/m), 0.1 V/m (range 200 V/m), and

1 V/m (range 600 V/m).

The sensitivity of the device (the lowest field it can measure within the specified error) is 0.2 V/m.

4. Current system can measure the fields as high as 600 V/m. Probe can withstand maximum field strength of 1,500 V/m (0.6 W/cm²) continuously, and its maximum pulse power density for 300 us pulses (duty cycle <1%) is at least 20W/cm².
