AC VOLTS: !
Plug in the test leads, black lead in “ —com” jack and red lead into “ +V mA"
jack. Select the proper AC voltage range with the range selector switch and
read directly on the corresponding AC voltage on the meter scale.
DC VOLT AND CURRENT:
Plug in the test leads, black lead in “ —com” jack and red lead into “ +V mA”
jack. Select the proper DC voltage on current range with the range selector
switch and read directly on the corresponding meter scale.
OHMS:
Plug in the test leads, black lead in “ —com” jack and red lead into * +
com” jack. Before measuring, check zero ohms indication by shorting the tips
of test leads together. If needle does not indicate zero ohms, adjust the zero
adjust control on the left side of the meter cabinet.

OPERATING INSTRUCTIONS
4,0000 MINITESTER
INSTALLING BATTERY:
Remove the back cover and insert the equivalent 1.5V penlight battery. Careful-
ly observe polarity and make certain that the battery is firmly seated.
SPECIAL NOTES:
1. TTC model employs a highly precision meter movement and extreme .
mechanical shock should be avoided.
2. Carefully observe polarity of test leads when measuring voltage or current.
3. When measuring an unknown voltage or current, select the highest range
first then work down to a suitable range for best reading.
4. The control on the left side of the cabinet is the zero adjust control for
ohms measurement.
5. When using the ohms range and needle will not zero properly by shorting
tips of test leads together, replace the battery. |

BATTERY INSTALLATION:
Remove the back cover from your multitester and insert “AA” size battery
into the bracket provided. Carefully observe polarity and be sure that the
battery is firmly seated with proper contact on each end.

NOTE for C1050:
Remove the red wire (being set on a printed circuit board on the zero
ohm adjust knob) which is shorted directly across the two termi -
nal screws on the back of the meter movement. This wire is placed
here at the time of manufacture to prevent damage in transport-
ation. This wire must be removed before your test will operate.
DC VOLTAGE AND CURRENT:
a) Insert the black test lead into the ( —) COM jack and the red test lead
in into the ( +) jack.
b) Select the desired range by turning the range selector knob.
с) For voltage measurements, the test leads are connected across the
load under test. DC current measurements are made with the test
leads connected in series with the circuit under test.
Observe proper polarities of the test leads carefully.
d) If the vollage or the current of*the circuit under test is not known,
the selector knob should be set at a high range and lowered scale at
a time to obtain satisfactory readings. To measure DC voltage in the
1200V range, insert the black lead into the (—) jack and the red lead
in the { +) 1.2KV DC jack setting the selector to 600 + 1.2K position.
AC VOLTAGE AND DECIBELS:
a) Insert the black test lead into the ( —) jack the red test lead into
20,000 OHMS/VOLT MULTITESTER
with leather case
c Curent. =
i -Decibel
the ( +) jack.
b) Select the range by turning the knob to the "ACV" section.
c) Decibel measurements for audio circuits are made with the test leads
in the same position. The inner decibel scale is graduated from —20
to +17 dB for 6V AC range and calibrated for 0 dB level of 1 milli -
watt on a 600 ohm line.
d) The polarity of the leads is not important.
RESISTANCE MEASUREMENTS:
a) Inseet the test leads into the ( —) and the ( +) jacks.
b) Select the range by turning the knob to x10 or xI1K.
c) Make SHORTING TEST before making measurements. Check the ZERO
ohm setting by shorting the test leads and adjusting the 0 ohm adjust
knob. The pointer is to be adjusted to “0" on the OHM scale.
d) Connect the leads across the resistor under test and read the top
scale by applying the proper multiplier, 10 or 1000.
e) When making resistance measurements of components wired in circuit,
be certain that the circuit power is turned off and also that one end
of the resistor or device under test is disconnected from the circuit.
f) Renew the internal battery when the SHORTING TEST fails to bring
the pointer to “0” on the OHMS scale.
OUTPUT MEASUREMENTS:
a) Audio output measurements can be made on circuits where DC is
present as in the output transformer circuits.
This instrument contains a blocking capacitor in series with OUTPUT
jack .
b) Insert the test leads into the OUTPUT and the ( —) jacks.
c) The output voltages are reads on the AC voltage ranges.
