4. The display shows the resistance value. (Maximum 99,9 Ω)
5. Disconnect the test probes to terminate the test.
6. On completion of testing switch to the [OFF] position. Alternatively auto
shut off operates after a period of instrument inactivity.
All continuity measurements are AUTO ranging from 0.00 Ω to 100 Ω on
Digital/analogue scale).
The MIT310A has manual range selection to 2 kΩ.
From 0.00 Ω to 10 Ω test current is greater than 200 mA. From 10 Ω to
100 Ω test current is greater than 20 mA. (See page 15 for MIT310A)
Test lead Null
(See page 14 for MIT310A)
Before using the continuity range or buzzer range for the first time, the test
lead resistance should be ‘zeroed out’. This ensures any measurement does
not include the resistance of the test leads.
1. Connect the test leads to the instrument and firmly short both leads
together.
2. Wait for the reading to stabilise and press the [TEST] button.
3. Display of the
z
confirms test leads zeroing. The display
should be 0.00 Ω.
Note:
Lead zeroing is retained when the instrument is switched off, or auto
shut-off operates.
To remove the ‘lead zero’ press the [TEST] button again.
Continuity test (MIT300, 310,320 and 330)
(See page 15 for MIT310A)
To make a continuity measurement:
1. Turn the instrument ‘On’ by selecting the continuity Ω range.
2. If required, zero test lead resistance, see test lead null (above).
3. Connect the test probes to the isolated circuit under test. The test will
start automatically.
