before making measurements.
4) When make measurement, selecting the proper
measurement range by starting at the largest anticipated
value and progressively selecting lower ranges the
measurement falls within the proper range.
5) Remove either of the test leads from the circuit under
test when changing the measurement range.
6) Operate the instrument only in the ambient temperature
range of 32 - 122蚌 (0 -50蚓) and less than 80 %
relative humidity.
7) Do not exceed the maximum rated voltage of each range
and input terminal.

ignition coil (or points).
c. Turn ignition switch to ON for a while. Display values
should indicate in LOW voltage value ( should under
1 V ). If not, bump engine until it reach.
d. If the above (c) point voltage display showed lower
than 0.2V, then the contact resistance of " Points " is
normal, or it need to be changed.
6)APPLICATION 2 : to check the " BATTERY
LEAKAGE " condition ( Used the DC 2V range )
a. Connect BLACK TEST PROBE to NEG (-) battery.
Connect RED TEST PROBE to various spots on the
surface of battery.

Leakage. Then clean acid or dirt from area around
battery with baking soda and water solution. Wipe dry.
7)APPLICATION 3 : to check the " BATTERY LIGHT
LOAD " ( Used the DC 200V or 20V range )

into the " Temperature Probe Socket " ( 3-5, fig 1 ) , take
care to observe the correct polarity.
2)Determine the 蚓 or 蚌 on the " Function Switch " and
select to the corresponding position.
3)
Consideration:
When the Thermocouple Probe is first plugged into the
meter, or if the probe is changed, the plug must be
allowed to stabilize at the same temperature of the
socket, which is in thermal contact with the cold junction
compensation device, if greatest accuracy is to be
achieved. This will only take a couple of minutes and
only applies if the plug of probe has previously been
exposed to an ambient temperature different ot that
meter.

4)Connect the RPM INDUCTIVE PICK UP SENSOR to
the HIGH TENSION WIRE of No. 1 SPARK PLUG (or
No. 2, No. 3... SPARK PLUG), ref. Fig 2, then the display
will show RPM reading (x 10 RPM).
NOTE:
a. RPM (TACH) used the "Secondary Tech"
measuring method, no matter what cylinder is
b. If the display reading is unstable, it may be caused

Only traditional ignition system car that built in
BREAKER POINTS needs to test DWELL ANGLE.
If the car in ELECTRONIC IGNITION SYSTEM need not.
5-8 Continuity Beeper
1)Select the " Function Switch " to the" " position.
2)Connect black test lead into " COM " terminal and red test
lead into " OHM " terminal.

forward current flow is established and the approx.
DIODE forward voltage(VF) values in volt will display
on the display reading. If the diode under test is
defective, " 000 " or near " .000 " value (short circuit) or
" 1 " ( open circuit ) will be displayed.
B. When connected as shown in Fig. 5, a reverse check on
the diode is made. If the diode under test is good, " 1 "
will be displayed. If the diode under test is defective,
" 000 " or other numbers will displayed. proper diode
testing should include both steps A and B above.
5-10 OP ADPT./Optional Adapter (External Adapter)
A. EXT ADPT. (External adapter):
This range is exactly same as " DC 200 mV " range. it
can match the external adapter (if this adapter is
built-in DC 200 mV output), such as PHOTO TACH.
TACHOMETER, LARGE CURRENT METER,
THERMOMETER....

This range is exactly same as "DC 200mV" range. It can
match the 200 A range of optional " DC/AC
CURRENT PROBE" ( such as CA-501, CA-202 ),
then can get current values on the meter display directly.
C. 2000A (2,000A DC/AC CURRENT PROBE):
This range is exactly same as " DC 2V " range but
without decimal point. It can match the 400 A or 2,000 A
range of optional " DC/AC CURRENT PROBE "
(such as CA-501, CA-202), then can get current
values on the display directly.
D. BATT TEST (Battery tester):
This range is exactly same as " DC 200 V " range. It can
match optional adapter of " BATTERY TESTER (with
a load) ", then can test the battery condition.
6. REPLACEMENT OF BATTERY
1)When the left corner of LCD display show "BAT" or " ", it
indicate a normal battery output of less than 6.5V - 7.5 V
It is necessary to replace the battery. However,
in-spec measurement may still be made for several
hours after LOW BATTERY INDICATOR appears
before the instrument become inaccurate.
2)Loose the Battery Cover Screw (3-7 Fig 1), slide the
battery cover away from the instrument and remove the
battery.
3)Replace with a 9V battery and reinstall the cover.
4)Make sure the battery cover is secured with the screw
after changing battery.
