6.1. Selecting the Appropriate Function and Range
When measuring AC voltage, DC voltage or resistance or when performing a continuity test, you should place the
function switch in the 200Ω
1000V position.
When measuring insulation resistance, you should place the function switch in the MANU., LOCK 1min., LOCK 2min.
or LOCK 4min. position. The device will produce a humming sound every 2 seconds and the display will show a
random reading if either the range or the function switch is in the wrong position.
6.2. Sonorous and Visual Alarm Signals
The device will emit a humming sound every two seconds and the red high voltage output indicator in the top right-
hand corner of the LCD will flash if the test button is pressed while the insulation range is selected.

6.3. Data-Hold Function

Simply toggle the hold switch to the right if you want to hold a particular value while measuring. The data-hold symbol
appears on the LCD. Slide the switch to the left again to leave the data-hold mode.
