1 Introduction
Thank you for purchasing a current clamp from PCE Instruments.
With the current clamp PCE-DC2 you can measure AC/DC voltages and currents, as well as the electrical
resistance. The clamp mechanism of the PCE-DC2 enables you to perform non-contact current
measurements, while voltage and resistance measurements can be done by using the included test
leads. Due to its compact design, the current clamp is well-suited for mobile application. With its built-in
flashlight and the display with backlight, the current clamp can even be operated in areas with poor
lighting conditions.

4.1 Battery replacement
To replace the batteries, lay the device face down on a soft surface. Next, open the cover of the battery
compartment on the back of the device. Remove the old batteries and replace them with new ones. After
that, close the battery compartment.
Note: Only use 1.5 V AAA batteries.
5 Measuring
Note: To avoid electric shocks, be very careful when measuring
current-carrying conductors.
Note: When using the clamp of the device, make sure there
is only one conductor at a time inside the clamp mechanism.
5.1 AC current measurement
1. Move the rotary control switch (3) to the “200 A AC”position.
2. Open the current clamp by using the opening button (6) and put the conductor to be measured
inside the clamp mechanism.
Note: Make sure there is only one conductor at a time inside the clamp mechanism.
3. You can now see the reading on the display

5.2 DC current measurement
1. Move the rotary control switch (3) to the “200 A DC”position.
2. Press and hold the zeroing button (4) for 2 seconds to perform a zeroing of the display.
3. Open the current clamp by using the opening button (6) and put the conductor to be measured
inside the clamp mechanism.
Note: Make sure there is only one conductor at a time inside the clamp mechanism.
4. You can now see the reading on the display
5.3 AC/DC voltage measurement
1. Connect the black test lead to the negative COM connector and the red test lead to the positive V
connector.
2. Move the rotary control switch (3) to the “V AC/DC” position.
3. Connect the test leads parallel to the component to be measured.
4. You can now see the reading on the display.
5.4 Non-contact voltage test
1. Move the top of the clamp close to the live conductor. For measuring purposes, it does not matter
if the conductor is insulated or not.
If you want to detect lead fractures move the current clamp along the conductor.
2. As long as the conductor is live, the signal lamp (8) is glowing.
Note: Electrostatic charging can also make the signal lamp glow.
5.5 Resistance measuring and continuity test
1. Connect the black test lead to the negative COM connector and the red test lead to the positive V
connector.
2. Move the rotary control switch (3) to the “Ω” position.
3. Connect the test leads to the component to be measured.
Note: It is best to disconnect the circuit to be measured before performing a test to prevent
interference with the reading.
4. Now you can see the reading on the display. If the resistance is below 30 Ω, the device plays an
acoustic alarm signal.
6 Additional functions
6.1 Flashlight
The current clamp comes with a built-in flashlight for working in areas with poor lighting conditions.
To turn the flashlight on, press the light button (2).

6.2 Display backlight
The display of the current clamp comes with a backlight. To activate it, press and hold the backlight
button (4) for 2 seconds. To turn the backlight back off, press and hold the button again for 2 seconds.
6.3 Display hold
You can freeze the current reading on the display at any time. To do so, simply press the Hold button (7).
By pressing the button again, you can unfreeze the reading.
6.4 Peak
If you are using the “200 A AC” measuring mode, you can press the Peak button (4) watch the peak
values. With this function, the device can capture peaks as fast as < 10 milliseconds in duration.
6.5 Max/Min function
You can use this function when using the “200 A DC”, the “V AC/DC” or the “Ω” mode.
Press the Peak/Max/Min (4) button to activate the Max/Min function. The display now shows the
maximum value and you can also see a “MAX” indication.
If you press the button again, the display shows the minimum value as well as a “MIN” indication.
Press the button once again to get to the MAX/MIN mode. In this mode the device shows the current
reading but stores and updates the minimum and maximum values at the same time.
To exit the Max/Min function, press and hold the Peak/Max/Min button for 2 seconds.
6.6 Zeroing of DC currents
By using this function, you can remove the offset values and improve the accuracy of the DC current
readings.
To do so, press and hold the zeroing button (4) for 2 seconds. A “Zero” indication appears on the display.
This means the offset value has been stored and removed from the readings.
To view the stored value, press the zeroing button. The “Zero” indication starts to flash and you can see
the value on the display.
To exit this mode, press and hold the zeroing button, until the “Zero” indication on the display disappears.
6.7 Auto power-off
The current clamp automatically shuts down after 7 minutes of idle time.
