The voltage indication on the display refers to the voltage at the DUT (device under test), and the accuracy is according to the DC voltage measurement. The marked test voltage and the actual test voltage may be different if the test voltage is adjusted in the Setup. Refer to the table below for more details. Ω Mega position (Mark) 1000 V 500 V 250 V 100 V 50 V Default test voltage (factory) 1000 V 500 V 250 V 100 V 50 V Deviation 2.0 V 1.5 V 1.5 V 1.5 V 1.0 V 0.2% 0.3% 0.6% 1.5% 2.0% Adjustable test voltage (user) 10 to 1100 V 10 to 600 V 10 to 300 V 10 to 120 V 10 to 60 V Incremental 1 V 1 V 1 V 1 V 1 V 2. Additional accuracy is to be added to the basic accuracy as shown in the table below. Voltage 1000 V 500 V 250 V 100 V 50 V Above 1 GΩ 500 MΩ 250 MΩ 100 MΩ 50 MΩ Basic accuracy 1.2% + 5 1.2% + 5 1.5% + 5 1.5% + 5 1.5% + 5 Additional accuracy 0.05%/GΩ 0.1%/GΩ 0.2%/GΩ 0.5%/GΩ 1.0%/GΩ |
