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 MIT481/2 and MIT485/2 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.
