4.
Adjust OHMS ADJUST CONTROL until meter reads zero ohms.
5.
Connect probes to component to be measured.
6.
Read ohms on OHMS scale (multiply value read by multiplier indicated by the switch).
A fuse protects the X1 range against accidental overloads If the fuse should blow, all OHMS ranges will not
operate.
DO NOT TOUCH circuitry while making measurements.
DISCONNECT or ISOLATE the device being tested from other circuitry.
NOTE: 1K equals 1000.
DC CURRENT MEASUREMENTS
0-.6 thru 0-600 Millamperes:
1
Insert test leads into VOM and COM lacks.
2
Set switch to appropriate mA range.
3
Connect the probes In series with the circuit (use alligator clips).
4
Turn circuit on.
5
Read current on black AC-DC scale.
The approximate voltage drop across the Model 310 is shown In the specifications Generally, this drop will
not affect the circuit But, In low voltage circuits, it may be necessary to compensate for this drop.
DISCONNECT POWER before connecting the Model 310 into the circuit.
