Earth/Ground Tester Specifications Operation: Central rotary switch and function keys Working temperature range: -10 °C ... +50 °C Operating temperature range: Nominal temperature range: 0 °C ... +35 °C 18 °C ... +28 °C Storage temperature range: -30 °C ... +60 °C Note The chart of four temperature ranges for the instrument exist to satisfy European Standards requirements; the instrument can be used over the full Working temperature range by using the temperature coefficient to calculate accuracy at the ambient temperature of use. Temperature coefficient: ± 0.1 % of range / Kelvin Operating errors: refer to operating temperature range and RH < 20 RE, RS < 100 RE The maximum percentage operating error within the measurement range does not exceed ± 30 % with the measured value as fiducial value, as determined in accordance with TABLE 1. The operating error applies under the rated operating conditions given in IEC1557-1 and the following: • injection of series interference voltages with system frequencies of 400 Hz, 60 Hz, 50 Hz, 16 /2 3 Hz or with d.c. voltage respectively across the terminals E (ES) and S. The r.m.s. value of the series inter- ference voltage shall be 3 V; • resistance of the auxiliary earth electrode and of the probes: 0 to 100 x RA but ≤ 50 kΩ; • system voltages between 85 % and 110 % of the nominal voltage and between 99 % and 101 % of the nominal system frequency for measuring equipment with a mains supply and/or measuring equipment deriving its output voltage directly from the distribution system. Limits of error: refer to nominal temperature range Climate class: C1 (IEC 654-1), -5 °C...+45 °C, 5 %...95 % RH Type of protection: IP 56 for case, IP 40 for battery door according to EN 60529 11

range / Kelvin
Operating errors:
refer to operating temperature range and RH
< 20 RE, RS < 100 RE
The maximum percentage operating error within the measurement range does
not exceed ± 30 % with the measured value as fiducial value, as determined in
accordance with TABLE 1.
The operating error applies under the rated operating conditions given in
IEC1557-1 and the following:
•
injection of series interference voltages with system frequencies of
400 Hz, 60 Hz, 50 Hz, 16

R
A
but
≤
50 k
Ω
;
•
