6. General operating instructions
Safety note:
If greater than 25 V appears on the circuit under test the instrument will default to a
voltage measurement and display the supply voltage.
On supply voltages over 50 V the instrument will be prevented from performing an insulation
test, protecting your instrument from damage.
Note: This limit is increased on MIT480, MIT481 and MIT485 to 75 V, but a warning
buzzer will indicate voltages above 50 V.
Use extreme care when using or measuring voltages above 30 V, particularly in high energy
systems.
Fused test leads are available as an optional accessory for local situations where increased
protection is required.
Hazardous voltages can exist on the insulation test range all the time the [TEST] button
is locked down.
