NOTE: Charge the instrument fully before use (Model 1060).

4.1 Measurement Procedure

• Start the instrument by selecting the corresponding position (MΩ, 40Ω
or 400kΩ) with the selector switch. All the segments on the LCD
screen are displayed, then the battery (or rechargeable battery) voltage
is displayed.
• Connect the leads to the "+" and "-" terminals and the points of
measurement.
• The input voltage is constantly measured and displayed on the small
display. If an external voltage is present that is greater than the thresholds
described in § 4.2, 4.3 and 4.4, then measurement is prohibited.
• 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 a voltage >25V
the instrument indicates this voltage on the small display, the warning symbol
flashes and the measurement is stopped.
Note: There are several special functions that can be used (see § 2.5).
4.2 Insulation Measurement
This function allows the instrument to measure insulation resistance from 1kΩ to
40GΩ at a test voltage of 50V, 100V, 250V and up to 1TΩ at 500V and 1000V.
• Use the rotary switch to select the required test voltage (MΩ-50V, or MΩ-
100V, or MΩ-500V, or MΩ-1000V).
• Connect the instrument to the insulator to be tested.
• Start the measurement using the START/STOP button and read the results.
WARNING: If the voltage present exceeds 8V for MΩ-50V, 16V for MΩ-100V, or
25V at all the other test voltages, then measurement is prohibited.
Scroll through the results on the main display with the R-DAR-PI 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.
