HOW TO READ DC MILLAMPS
1. Connect Red short Probe in + Jack, Black in - Jack.
2. Read all DC Milliamp Ranges on the second arc down.
3. For current measurements, open the circuit and connect the instrument in series with
the circuit being measured.
CAUTION
Make certain that the circuit to be measured is completely De-Energized (DEAD) with NO
live voltage in the circuit whatsoever.
Before taking any resistance measurement, disconnect line voltage fro circuit being
measured, or feeder voltage from any component being checked.
HOW TO READ OHMS
1. Set Range knob selector to suitable OHM Range.
2. Connect Red short Probe in + Jack, Black in – Jack
3. Short the Long Prod handles and adjust the Zero Ohm adjust pot (see Fig. 1) until the
pointer is directly over the Zero position on the Ohm Range (at extreme right).
Note: If Ohm Zero position cannot be adjusted, change the battery
4. Touch the long prod handles across the circuit, or component to be measured and
read on the Ohm arc. (Top Arc).
IMPORTANT - PLEASE READ CAREFULLY
Impressing live voltage across the Ohm circuit by mis-use or abuse may result in injury to
the operator and/or damage to the instrument and the equipment being checked. The extent
of the damage will depend on the volts and amps going at time of measurement.
CAUTION
Make certain that the circuit to be measured is completely De-Energized (DEAD) with NO
live voltage in the circuit whatsoever.
Before taking any resistance measurement, disconnect line voltage for circuit being
measured, or feeder voltage from any component being checked.
HOW TO USE THE BATTERY CHECK RANGES
1. The SP-10A comes with two separate battery check ranges that enable you to test either
1.5VDC or 9VDC batteries
2. Connect Red short Probe to + Jack, Black to - Jack.
3. Set the range selector switch to the 1.5V battery test range
4. Connect the test leads to the 1.5VDC battery under test. A good 1.5VDC battery will
read in the green portion of the Arc.
5. To check 9V batteries follow the above procedures with the range selector switch set
to 9V.
6. The “REPLACE” section of the scale plate shows that the battery may be starting
to decay.
Note: May not read various 1.5VDC button cell batteries.
