WARNING: DO NOT APPLY VOLTAGE TO MEASURING
TERMINAL WHILE MAKING ANY CAPACITANCE
MEASUREMENTS.
BEFORE TESTING ANY CAPACITORS, DISCHARGE THE
CAPACITOR COMPLETELY.
BEFORE MEASUREMENTS, PLEASE READ THE
INSTRUCTIONS OF MT-2007-C CAREFULLY.
1. For measuring the Capacitor over 25uF:
1) Set the selector switch to the R X 1K range.
2) Connect the BLACK test lead to the “-COM” jack and the
RED test lead to the Red “+” jack.
3) Connect the test leads to the capacitor to be measured
(Note the polarity of capacitor).
4) Watch the needle deflection to the right topside, and read
the Red C1 scale on the Dial.
2. For measuring the little Capacitor less than 25uF:
1) Set the selector switch to the DC 50uA (C2) range.
2) Set the capacitance selector switch on the MT-2007-C to
the proper range.
3) Plug the BLACK wire terminal of the MT-2007-C to the
“-COM” jack and the RED wire terminal of the MT-2007-C
to the Red “+” jack.
4) Insert the capacitor to be measured directly into the Cx
Jacks on the MT-2007-C (Note the polarity of capacitor).
5) Set-On the Power switch on the MT-2007-C, and then the
LED lighting.
6) Read the A.V. C2 (250uF) scale on the Dial and multiply it
as per the multiplication table shown below:
13
.Capacitance RANGE Multiplication Factor
0.025uF X 0.0001
0.25uF X 0.001
25uF X 0.1
After measurement, turn-off the power switches either of the
MT-2007-C, or of the tester.
TROUBLESHOOTING
Nevertheless, problems or malfunctions may occur.
For this reason, the following is a description of how you can
eliminate possible mal-
functions yourself:
Error Possible cause
The multimeter does not
work.
Are the batteries exhausted? Is
the power indicator lit? Check
the state of the batteries and the
fuse 0.5A.
No measurements possible
via V/mA socket.
Is the fuse defective? Check the
fuse 0.5A (fuse replacement)
No change in measured
values.
Have you selected the right
measuring sockets? Is the
measuring range/mode correct
(AC/DC)?
Faulty measuring results
are displayed.
Has null balancing of the display
or a 0 Ohm calibration for the
resistance measurement been
carried out? Is the batteries not
properly assembled in?

MAINTENANCE
Replacement for Battery and/or Fuse should only be done
after the test leads have been disconnected and POWER OFF.
1. Battery Replacement
1). Note the condition of the batteries using the procedure
described above, if the battery needs to be replaced,
remove the screw and open the upper cover of the battery
cabinet on the rear case.
2). Take off the spent batteries and replace them with a battery
of the same type. Observing polarity as indicated battery
polarity marking on the bottom of the battery compartments.
3). Replace the battery cabinet cover and tighten the screw.
2. Fuse Replacement
1). When the fuse needs replacement, use only UL-Listed
0.5A/250V fuse identical in physical size to the original type
5 x 20 mm.
2). Disassemble the side Holsters, and take off the screw, then
open the whole rear case. Remove the old fuse from its
holder; install the new fuse into it.
3). Replace the rear cover & Holsters, and tighten the screw.
