NOTE: Charge the instrument fully before use.
4.1 MEASUREMENT PROCEDURE
■ Start the instrument by turning the switch to the corresponding position. All
the segments on the LCD screen are displayed. Then, the battery voltage is
displayed.
■ Connect the leads to the "+" and "-" leads to the measurement points.
■ The voltage is continuously measured and displayed on the small display.
■ Press the START/STOP button to start the measurement.
■ Press START/STOP again to stop the measurement. The last result remains
on the display until the next measurement is started, or the selector switch is
turned.
WARNING: If an external voltage is present that is greater than the
thresholds described in §3.2, the instrument indicates this voltage on
the small display, the warning symbol flashes, and the measurement is
stopped.
There are several special functions that can be used (see §2.6).
4.2 INSULATION MEASUREMENT
This function allows the instrument to measure insulation between 10kΩ and
10TΩ at a test voltage of 500V, 1000V, 2500V, and 5000V or programmed
voltage between 40V and 5100V.
■ Use the rotary switch to select the required test voltage (MΩ-500V, or MΩ-
1000V, or MΩ-2500V, MΩ-5000V, or Var. MΩ-50-5000V).
■ Connect the instrument to the insulator to be tested.
■ Start the measurement using the START/STOP button and read the results.
WARNING: If an external voltage is present that is greater than the
thresholds described in §3.2, then measurement is prohibited.
Scroll through the results on the main display with the R-DAR-PI-DD button or on
the small display with the V/TIME button.
Use R(t) when carrying out a 'time-controlled test' to scroll through the interval
measurement values saved at the sampling rate specified in SET-UP. These
values are available until another measurement is taken or the selector switch is
turned.
When measuring high levels of insulation (>1GΩ), it is advised that the "G"
guard terminal be used to eliminate the influence of surface leakage currents.
