Intended use of the Escort 97 measuring
instrument:
DC voltage measurement up to a maximum of 1000 VDC
True RMS measurement of AC voltages to 750 VACrms maximum
True RMS measurement of mixed voltages (AC + DC) to
750 VACrms/VDC max.
True rms measurement of DC and AC currents up to 10 A max. for
30 s max. (protected)
Resistance measurement up to 40 MOhm max
Frequency measurement up to 200 kHz max
dBm measurement from -80.79 to 81.48 dBm
Measurement of temperatures from -40° C to 1372 °C via an exter-
nal temperature sensor.
Capacitance measurement from approx. 10 pF to approx. 10000 µF
Continuity checking and diode test
Signal generator operation from 0.5 Hz to 4800 Hz
A measurement must not be performed under unfavourable am-
bient conditions. Unfavourable ambient conditions include:
- moisture or excessive humidity,
- dust and combustible gases, fumes or solvents,
- thunderstorms or storm conditions such as strong electrostatic
fields, etc.
Any use other than as described above can lead to damage to the
instrument; in addition this is accompanied by dangers such as
short circuit, fire, electric shock, etc. No part of the product must
be modified or converted! The safety instructions are to be follo-
wed without fail !
