9.5 DIODE AND CONTINUITY
range
Overload protection: F0.5 A/500 V fuse
9.6 NON-CONTACT AC VOLTAGE DETECTION
Test voltage range: 90 V-1000 V AC rms
The built-in buzzer will sound when live voltage is detected.
10. Operation

10.1 DC VOLTAGE MEASUREMENT

Do not measure circuits that may contain voltages > 500 VDC or
> 500 VAC
Use extreme caution when measuring voltages higher than 60 VDC
or 30 VAC rms.
Always place your fingers behind the protective edges of the test
probes while measuring!
1. Set the rotary switch in the desired "
2. Connect the red test lead to the "VmA" jack and the black lead to the
"COM" jack.
3. Connect the test leads to the source being measured.
4. Read the voltage value and the polarity of the red test lead on the LCD
display.
Notes
 If the range is not known beforehand, set the selector switch to a high
range and lower gradually.
 An over-range is indicated by 1 or -1. Set to a higher range.
 The maximum input current is 500 V rms.
