A-2 Physical Characteristics HVM200 Manual
Effects of Temperature
The RMS level varies 0.5 dB when the complete instrument is tested over the - 10° C to 50° C
temperature range. The reference reading, for this test, is taken at 20° C and 36% relative humidity
(RH); the input signal is at 79.6 Hz.
Effects of Humidity
The RMS level varies 0.5 dB when the complete instrument is tested over the 0% to 90% RH,
noncondensing range. This test is performed at 40° C, with an input signal of 79.6 Hz.
Limits of Temperature and Humidity
Permanent damage can occur when stored or operated above 60° C or below -20° C.
Effects of Magnetic Fields
The RMS level varies 0.5 dB when the complete instrument is tested in an 80 A/m, 60 Hz magnetic
field (worst case orientation).
Effects of Mechanical Vibrations
The instrument meets the specifications for susceptibility to vibration in accordance with ISO
8041:2005(E) section 7.1.
Stabilization Time
At power-on, allow the instrument to stabilize, approximately 20 seconds, prior to performing any
measurements. When changing sensors, allow 10 seconds of stabilization time prior to performing a
new measurement.
