Intended Use
The Pentype multimeter is a digital measuring device with a LCD. The pen form allows the measured values to be read off while the measurement can be carried out with both hands.
The auto-range multimeter possesses the following measuring feature
- Measurement of direct and alternating voltage up to a maximum of 250 V
- Measurement of direct and alternating current up to a maximum of 400 mA (only VC-86)
- It is also designed to measure resistance values of up to 40 MOh (VC-82 bis 20 MOhm).
- Continuity check (< 35 Ohm acoustic) and diode test.
The measured impedance can be reduced to suppress phantom voltage values briefly (!) (only VC-86).
The measurement device may not be operated when it is open, i.e. with an open battery compartment or when the battery compartment cover is missing. Any measurement in moist rooms or outdoors or under adverse ambient conditions is not permitted.
The following are unfavourable ambient conditions:
- Excessive dampness or humidity
- Dust or combustible gases, vapours or solvents
- Electrical storms or stormy conditions and strong electrostatic fields, etc.
The pen-type multimeter may only be used in areas of the overvoltage category CATII to 250 V and CATIII to 250 V.

In commercial institutions, the accident prevention regulations of the Employer's Liability Insurance Association for Electrical Systems and Operating Materials are to be observed.
In schools, training centres, computer and self-help workshops, handling of measuring devices must be supervised by trained personnel in a responsible manner.
Always make sure before measuring voltage that the measuring device is not in a currnet measuring area.
The voltage between the two measuring contacts of the measuring device and the earth may not exceed 250 V DC/AC in overvoltage category III or 250 V DC/AC in overvoltage category II.
Before changing the measuring area, the test prods have to be removed from the measured object.
Take particular care when dealing with voltages exceeding 25 V AC or 35 V DC. Even with voltages as low as these, it is possible to receive a life-threatening electric shock if you touch electric conductors.
Prior to each measurement, check your instrument including its measuring lines for damage. Never carry out measurements when the protective insulation is damaged (ripped, torn off etc.).
In order to avoid an electric shock, ensure that you do not touch the connections to be measured, even indirectly, during measurements.
Do not use the clamp-on ammeter just before, during or just after an electrical storm (electrical shock! / high-energy over-voltages!). Please make certain that your hands, shoes, clothing, the floor, the measuring device or the measurement lines switches and switching parts are absolutely dry.
Do not operate the measuring instrument in areas or unfavourable conditions where combustible gases, vapours or dust are or may be present. Avoid operation in the immediate vicinity of:
- strong magnetic or electromagnetic fields
- transmitting aerials or HF generators.
These could falsify the measured value.
If you have reason to assume that safe operation is no longer possible, then disconnect the appliance immediately and secure it against inadvertent operation. It can be assumed that safe operation is no longer possible if:
- the device shows signs of visible damage,
- the device no longer functions and
- it has been stored for longer periods under unfavourable conditions or
-following considerable stress during transportation.
Do not switch the measuring instrument on immediately after it has been taken from a cold to a warm environment. The condensation that occurs could destroy the device. Allow the device to reach room temperature before switching it on.
Do not leave the packaging material lying around carelessly. Plastic films and/or bags and polystyrene parts etc. may become dangerous toys in the hands of children.
Before opening it, disconnect the device from all voltage sources.
Capacitors in the device may still be charged, even if the device has been disconnected from all voltage sources. You should also heed the safety instructions in each chapter of these instructions.

Carrying out measurements
Never exceed the max. permitted input volumes in the overvoltage categories II or III (domestic and commercial area).
The frequency of the change volumes may not exceed 400 Hz!
Do not touch any circuits or circuit parts if voltages greater than 25 V ACrms or 35 V DC could be pend there! Danger to life!
Before measuring, check the measuring line for damage such as, for example, cuts, cracks or squeezing.
Defective measuring lines may no longer be used! Danger to life!
To guard against injury through the measuring prods on the pen-type there is a protection cap. This protection cap can be inserted when it has been removed into the safe-keeping opening (11) on the front.
Measuring prod selection
On the pen-type multimeter, the measuring prod can be replaced simply by the enclosed 70 mm second tip This is used fo measurement on lower lying measuring points.
Screw the measuring prod off in the anticlockwise direction and replace it with the long measuring prod.
The enclosed crocodile clamp can be screwed on the black measuring line.
Make sure when measuring the measuring prods that all voltage sources have been removed from the measuring device
Voltage measurement
Proceed as follows to measure dc voltages:
text_image
Diagram of an electrical circuit setup with a lamp, resistor, galvanometer, and two probes connected to a power source.- Turn operating switch (10) to position "V"
- Now connect the two measuring prods to the object to be measured (battery, switch etc.).
- the polarity of the measuring figure concerned will be displayed in display together with the current measuring value in the display (6
To measure alternating voltage (AC), press button "S" (5) to change to the AC-rang. if you press it again, it will switch again to the DC measuring range.
The voltage range "V" shows an input resistance of approx. 10 MOhm. As soon as for direct voltages a minus "-" appears before the measuring figure, the measured voltage is negative (or the measuring prods have been interchanged).
"LI" Low Impedance 400 Ω (only VC-86)
This function may only be used for voltages of a max. of 250 V and a max. of 3 seconds!
This measuring function enables the reduction of the measuring impedance from 10 Ω to 400 Ω. through the reduction in the measuring impenace, possible phantom voltages are suppressed which could falsify the measuring result.
Press key "LI" (7) during the voltage measurment (max. 250 V) for a max. of 3 seconds. After release, the multimeter has the normal measuring impedance of 10 Ω.
Resistance measurement/continuity test
Make sure that all the circuit parts, switches and components and other objects of measurement are disconnected from the voltage at all times.
natural_image
Illustration of a power tool connected to a resistor and two probes (no text or symbols)Proceed as follows to measure resistance and for the acoustic continuity test:
- Turn range selection switch (10) to position "Ω"
- Check the measuring lines for continuity by connecting both measuring prods to one another. After that the resistance value must read approx. 0 Ohm.
- Now connect the measuring prods to the object to be measured. As long as the object to be measured is not high-resistive or is interrupted, the measured value will be displayed in the display (6).
When you carry out a resistance measurement, make sure that the measuring points which you contact with the measuring prods are free from dirt, oil, soldering vanish or similar Such circumstances can falsify the measured result
For the continuity check, press button "S" (5) until the symbol appears in the display. If you continue to press it, you will switch to the next measuring area (dode test, resistance, continuity ...).
As soon as "OL" appears in the display, you have exceeded the measuring area or the measuring circuit has been broken.
Diode test
For this measurement, proceed as follows:
natural_image
Illustration of a soldering iron and its corresponding schematic symbol (no text or labels)- Switch area selection switch (10) to position 9.
- Press button "S"(5) twice to switch over to the diode test area. The diode symbol appears in the display.
- Now connect the two measuring prods with the object to be measured (diode). The conducting-state voltage is displayed.
If you test a diode in the conducting direction(rred measuring prod on the anode = diode side without ring marking), you will measure a voltage from approx. 0.6 V (silicon diode), as long as the diode route is not defective.
If you measure on the other hand in the blocked direction (red measuring line on the cathode = diode side with ring marking), "OL" will appear in the display.
If, on the other hand, a "voltage figure" is displayed, you have either connected the object to be measured incorrectly or it is defective.
Current measurement (only VC-86)
Currents of up to 400mA can be measured in the current measurement area. The current measurement area is secured and thus protected against overloading.
Proceed as follows to measure dc currents:
natural_image
Illustration of a simple electrical circuit with a pen, bulb, and variable resistor (no text or symbols)- Turn range selection switch (10) to position "A"
- The polarity of the measuring figure concerned will be displayed in the display together with the current measuring value in the display (6).
Proceed as follows to insert or measure alternating currents:
- Press button "S" (5) in the current measurement area, to change to the AC area; if you press it again, you will switch back to the DC area.
- The polarity of the measuring figure concerned will be displayed in the display together with the current measuring value in the display (6).
Never operate the measurement device when it is open.
Max-Hold Function (only VC-82)
The VC-82 has a MAX-Hold Function. If you press during a measuring the MAX button (7), the item shows automatically the highest measuring value on the LCD (6). To deactivate this funktion, press MAX button (7) again.
Auto-Power OFF function
So as not to reduce the service life of the battery unnecessarily, an automatic switch-off as been installed. The measuring device is switched off if no button is pressed for 10 minutes or the slide switch has not be oeprated. Simply by pressing any desired button (with the exception of "LI") the measuring device can be switched on again.
Servicing and cleaning
With the exception of replacing the fuse/battery and occasional cleaning, the pen-type multileter is maintenance-free. Use a clean, lint-free, antistatic and dry cloth to clean the device. Do not use any abrasive or chemical agents or detergents containing solvents.
Replacing the Fuse (only VC-86)
lef mo measure value is displayed any longer in the power measuring area, the fuse is presumably defective.
Proceed as follows to replace the fuse:
natural_image
Diagram of a missile or projectile with directional arrows indicating motion (no text or symbols)- Switch off the multimeter and remove the measuring device from all measuring circuits.
- Turnothe red measuring pond on the corrugated plastic ring in the anticlockwise direction and remove the prod.
- Remove the light-grey covering towards the front.
- Replace the defective fuse with a new fine-wire fuse (5 x 20 mm) the same type and rated current (F500mA, 250V)
- Close the pen-type multimeter again carefully in the reverse order
Make sure that only fuses of the type stated and rated current specified are used as a replacement. The use of repaired fuses or bridging the fuse bracket is not permitted.
Never operate the measurement device when it is open. !Danger to life!
