Getting Started:
The PA-699 current probe enables a general purpose oscilloscope to
display AC and DC current signals up to 80 amps Peak (28ARMS). The
PA-699 current probe can also make AC and DC measurements with a
multimeter by using the recommended accessory MT-246N
(BNC-to-banana) plug adapter.
Figure 1: shows the controls and indicators on the PA-699 current probe.

Control/Indicator Description
Current flow symbol. The arrow shows the probe’s
polarity convention for measuring current flowing
from positive to negative.
Zero adjustment. Rotate to adjust the probe output
to zero when there is no current present. It may also
be used to offset a DC signal component. Zeroing is
not needed for AC measurements unless your
instrument cannot isolate a DC component (if
present).
OFF/Range switch. Slide the switch from OFF to
either the 0.1V/A or 1V/A range. When either range is
selected, the probe is turned on, and the green
battery indicator lights. If the indicator does not light,
see Battery Notes and Battery Installation on page11.
Battery indicator. The green battery indicator lights
when the probe is turned on. For more information,
see Battery Notes and Battery Installation on page11.
Overload indicator. The red overload indicator lights
if the measured signal is greater than the selected
range capacity. Switch the probe to 50 mV/A if
possible, or remove the probe from the circuit.

Basic Operation:
Before using the probe, the batteries or specified power adaptor must be
installed. See the battery installation instructions on page11.
WARNING!
Do not clamp the probe onto circuits with voltages greater than 600
VAC. Personal injury or damage to the probe may result.
Always connect the PA-699 current probe output to the instrument
before clamping onto the circuit under test.
1. First connect the current probe BNC connector to BP-250 (double BNC
connection cable) then connect to oscilloscope input. Start by setting the
oscilloscope voltage input channel to DC volts, and the voltage sensitivity
scale to 0.1 V/div.
2. Move the OFF/ Range switch to the 0.1V/A or 1V/A position to turn on
the probe.
(※The PA-699 current probe has a green LED power/battery indicator. If
the LED does not light, replace the battery or use specified power
adaptor.)
3. Use the ZERO adjustment to zero or offset the probe output detection of
residual magnetic DC charges.
4. Connect the probe to the circuit by opening the jaws and clamping
around the conductor. See Figure 2.
NOTE. Clamping around both the “hot” and neutral wires may give
you a zero reading.
(Remember to unclamp the probe from the conductor before
disconnecting it from your meter or instrument).
Figure 2: Connecting the PA-699 current probe.

5. Adjust the probe channel and oscilloscope’s time base as necessary to
get a clear and stable view of the signal. Set the oscilloscope input to DC
volts to see both theAC and DC currents; set the channel to AC to see
the AC current only.
The current drawn by different devices look much different than that of
others. While the RMS current can only be used in low frequency current,
the momentary peaks may be quite high. Figure 3 shows the difference
between the line current drawn by a resistive load and a motor controller.
Figure 3: Typical current waveforms
Congratulations on your purchase of the PA-699, a multifunctional current
probe. When connecting to a digital meter, use the recommended
MT-246N (BNC-to-banana adapter). Connect the black lead to the meter
COM (black letters on the meter), and the red lead to the VΩinput (red
letters on the meter).
To measure only AC current, set the meter to measure AC volts.
To measure DC current, set the meter to measure DC volts. Note the
current convention arrow on the probe to get the proper polarity reading.
To increase the measurement sensitivity of the PA-699 current probe, loop
additional turns of the wire under test through the jaws. See Figure 4. The
sensitivity of the PA-699 current probe is multiplied times the number of
loops in the jaws. For example: 1V/AX 4 turns = 4V/A.

Maintenance:
Use the information in this section to properly maintain the operation of
your PA-699AC/DC Current Probe.
1. Notes on Battery and Power Converter:
The PA-699 current probe uses a single square 9 V battery. This machine
is a high power product. Please use the specified alkaline battery.
As the battery in the PA-699 current probe is drained, significant gain
errors may occur. The green LED will continue to light until a low battery
voltage of 6.5 V is reached.
If probe gain errors are detected, replace the battery with a fresh one.
As an alternative, an AC power converter can be used to avoid gain error
due to poor battery durability. Switch to a square 9V battery only when
there is no AC power supply available outdoors.
When using an AC power converter for an extended time, we suggest you
remove the battery from the compartment. This is because heating will
result in battery leakage, and battery electrolyte will rust the circuit board,
thus creating major damage. Furthermore, batteries are high pollution
products and therefore by reducing their usage, we will in turn protect the
environment.

11
PA-699 has in its design a priority external power circuit therefore it is safe
to simultaneously install the battery and the external power supply. During
usage, removing the external power supply will not produce waveform
anomaly or any damage. However when external power is used for an
extended time (more than 1 week), removal of battery is recommended.
This will avoid leakage of battery since the quality of the batteries is
something that is out of our control.
2. Battery Installation:
(1) Remove the probe from the circuit.
(2) Open the battery compartment by loosening the three screws (uses
standard 3x15) and take the cover off. Install/replace the battery.
(3) While observing polarity, attach the new alkaline battery to the battery
connector buttons and place the battery in the specified area.
(4) Place the cover back and lightly tighten the screws to hold the cover in
place.

3. Cleaning:
To clean the probe exterior, use a soft cloth dampened in a solution of mild
detergent and water. To clean the core, open the jaw and clean the
exposed core surfaces with a cotton swap dampened with isopropyl
alcohol (isopropanol). Lubricate the jaws mating surfaces with light oil.
Do not clean with solvents or abrasives. Do not immerse the probe.
4. Preparation for Shipment
Our company has designed a special box to be used for PA-699,
convenient for storage and shipment. Please do not discard it.
If the original packaging is unfit for use or not available, use the following
packaging guidelines:
(1) Use a sturdy shipping carton having inside dimensions at least one inch
greater than the probe dimensions.
(2) Put the probe into a plastic bag or wrap to protect it from dampness.
(3) Place the probe into the box and stabilize it with light packaging
material.
(4) Seal the carton with shipping tape.
