DVM6013 – DIGITAL CAPACITANCE METER
1. General
a) Introduction
Thank you for buying the DVM6013. This digital capacitance meter gives a direct reading of capacitance on a 3 ½-
digit LCD display. Nine ranges provide precise readings from 0.1pF to 20mF, which includes virtually all capacitors
used in maintenance services, schools, etc. The DVM6013’s limited weight and small size make it a user-friendly
device.
b) Features
LCD display with character height 21mm, 1999 counts.
9 ranges from 200pF to 20mF
very accurate measurements
external zero adjuster : ±20pF
dual-slope integration A/D converter
overload indication : “1
safe test probes
dimensions : 31.5 x 91 x 189mm (H x W x L)
weight : 240g (battery included)
2. Specifications
Maximum accuracy is achieved during a one-year period after calibration. Ideal circumstances require an operating
temperature of 18 to 28°C (64 to 82°F).
Power Supply 9V-battery NEDA1604 or 6F22 006P
Battery-Low Indication the “ ” symbol is displayed
Fuse 200mA/250V
Excitation Voltage 2.8V peak MAX
Operating Temperature 0 to +40°C (+32 to +10F)
Storage Temperature -10 to +50°C (+14 to +122°F)
Range Resolution Accuracy Test Frequency
200pF 0.1pF ± 0.5% of full scale ± 1 digit 800Hz
2nF 1pF ± 0.5% of full scale ± 1 digit 800Hz
20nF 10pF ± 0.5% of full scale ± 1 digit 800Hz
200nF 100pF ± 0.5% of full scale ± 1 digit 800Hz
2 F µ1000pF ± 0.5% of full scale ± 1 digit 800Hz
20 F µ0.01µ F ± 0.5% of full scale ± 1 digit 80Hz
200 F µ0. F ± 0.5% of full scale ± 1 digit 8Hz
2000 F µ1µF ± 1.0% of full scale ± 1 digit 8Hz
20mF 10µ F ± 2.0% of full scale ± 2 digits 8Hz

WARNING
Make sure that the battery is correctly inserted into the battery compartment and connected to the battery snaps.
Observe the polarity indications when connecting polarised capacitors. Discharge all capacitors fully.
Do not apply any voltage to the test jacks because serious damage may ensue.
Do not short the test leads together as this will increase the battery’s power consumption drastically. The LCD will
display an overrange indication for all ranges.
OPERATION
If no capacitance value is displayed : start with the 200pF-range and select the next range until the overrange
indication is replaced by an actual measured value.
A shorted capacitor generates an overrange indication on all ranges. A capacitor with a low leakage voltage will
generate either an overrange indication or an unusually high measured value. With an open capacitor, the display
will read “0” for every range (possibly just a few pF for the 200pF-range).
Measure very low capacitances using very short leads or the capacitor-measuring socket above the input jacks on
the front panel. This will allow you to avoid introducing any stray capacitance.
When using the optional test leads to measure small values, you should keep in mind that the leads may
introduce a small capacitive charge. Connect the leads and check the display. Subtract the displayed value from
the eventual measuring result. Obviously, it would be easier to use the zero adjuster on the front panel…
Capacitors, and electrolytic capacitors in particular, are notorious for their great tolerance. You should not be
surprised, therefore, if the measured value is higher than the value on the capacitor, unless when using a
capacitor with low tolerance. However, only on the rarest of occasions will the measured value be much lower
than the rated value.
You can locate a leaking capacity if the value changes considerably when you select a different scale. The effect
of the internal leakage resistance is limited in the lower ranges.

CAPACITANCE MEASUREMENTS
1. Select the desired range.
2. When selecting the 200pF-, 2nF- or 20nF range, you should adjust the zero prior to connecting the capacitor in
question but after connecting the test leads. The zero adjuster can make a max. adjustment of ± 20pF.
3. Connect the capacitor to the measuring socket through the alligator clips or insert it directly into the measuring
socket above the input jacks on the front panel.
4. The measured value is displayed directly on the LCD and the electrical unit is indicated (pF, nF, µ F, mF). The
number “1” indicates that the measured value is outside the selected range (“overrange indication”). If the
measured value has one or more leading zeros, you should select a lower range in order to improve the
resolution of the measurement.
5. Place the rotary adjustment in the OFF-position after use.
5. Maintenance
Replace the battery when the “ ” symbol is displayed. Remove the screws on the back cover and open the
case. Insert a new 9V-battery (NEDA1604 or 6F22 006P) and close the battery compartment.
The fuse only rarely needs to be replaced. A blown fuse is nearly always the result of an operator error. Open the
case, then take the PCB out from the front cover. Replace the blown fuse with a new one with the same ratings
(200mA/250V quick-acting).
If any faults or abnormalities are observed, the meter cannot be used anymore and has to be checked out.
Never use the meter unless the back cover is in place and fully fastened.
Do not use abrasives or solvents on the meter, use only a damp cloth and a mild detergent.
6. Accessories
The DVM6013 is supplied with test leads, a 9V-battery (NEDA 1604 or 6F22 006P), a manual and a holster. The
holster can be used to place the device upright on a table or to hang it from a nail in the wall.
