1 Introduction
Thank you for purchasing a PCE-DC 41 from PCE Instruments.
This instrument is highly versatile in power system maintenance as it has several functions. It is not only
very reliable in measuring power, it can also measure voltage, current and continuity at high accuracy.
Measurement results are easily readable from the 4-digit LC display with backlight. The device’s special
features are its Peak Hold and Data Hold functions, its Auto Zero function as well as an Auto Power Off
function which turns off the meter after 30 minutes of inactivity. The instrument comes with batteries, a
test lead, a carrying case and an instruction manual.
2 Safety notes

4.3 Key functions
4.3.1 HOLD function
You can freeze the current value in the display by pressing the HOLD key. To deactivate this function,
press the HOLD key once again.
4.3.2 PEAK function
When you press the PEAK key, the PEAK icon will appear in the display. The highest value will be
displayed and frozen in the display. This value is updated anytime a higher value is measured. To return
to normal mode, press the PEAK key again.
4.3.3 Zero function
When you press and hold the PEAK key for at least 2 seconds, the icon will be shown. This means
that the zero function is activated, i. e. that the reading is reset to zero. To return to normal mode, press
the PEAK key again.
4.3.4 Backlight function
You can turn on the backlight function by pressing the key. The backlight is a yellow light which will
shine for 15 seconds when activated. To turn off this function, press the key again.

For safety reasons, it is recommended to
disconnect the test leads from the meter
before carrying out this measurement.
Then switch the main function selector to
. Open the clamp by pushing the lever
and insert the cable to be measured into
the hole. When the cable is kept at the
centre, this will ensure most accurate
results. Close the clamp and read the
result from the LCD. It might occur that the
result is hard to read. In this case, press
the HOLD key and read the result at a
later stage.

5.1.5 Resistance measurement
Before taking a resistance measurement, make
sure that the power is cut off from the circuit and
that all capacitors are discharged. Then switch the
main function selector to . Connect the red
test lead to the + terminal and the black test lead to
the COM terminal. Touch the points to be tested
with the tips of the test leads and read the result
which will appear in the LCD.
Switch the main function selector to .
Connect the red test lead to the + terminal and
the black test lead to the COM terminal. Place the
tips of the test leads at the points where you wish
to carry out the continuity test. If the resistance is
below 40 Ω, the beeper will sound continuously.

5.2 Battery replacement
When the battery voltage drops below a sufficient level, the icon will appear in the display. When this
happens, please replace the battery.
Before doing so, switch the function selector to OFF and disconnect the test leads. Use a screwdriver to
open the battery compartment cover. Replace the used batteries with two new 1.5 V AAA batteries. Close
the battery compartment cover and fasten the screw.
For the disposal of batteries, the 2006/66/EC directive of the European Parliament applies. Due to the
contained pollutants, batteries must not be disposed of as household waste. They must be given to
collection points designed for that purpose.

give them to a recycling company which disposes of the devices in line with law.
If you have any questions, please contact PCE Instruments.
5.3 Maintenance
Warning!
Before opening the meter, disconnect both test leads and close the cover.
Caution!
To avoid contamination or static damage, do not touch the circuit board without proper static protection.
