Resistance Measurements

1. Insert the black test lead into the negative COM terminal and
the red test lead into the OHMS positive terminal.
2. Set the Range switch to the X1Ω or X100Ω position as

until the pointer is over the 0 ohms position.
6. Touch the test probe tips across the circuit or component under
test.
7. The analog display pointer will indicate the resistance reading.

Temperature Measurements

Zero procedure (fig. 1)
1. Insert the temperature probe black plug into the COM terminal and the Probe tip
into the V Ω terminal.
2. Adjust the pointer for a 0 Ω scale reading
Measurements (fig. 2)
1. Insert the temperature probe black plug into the COM terminal and the red plug
into the V Ω terminal.
