Before you start

1

Check kit contents and part quantities/values by the photo at right and part list in page2
and page 3. Report missing or wrong parts to your vendor.

Resistor values are easy to mis-read. It is strongly suggested to check their values

2

by ohm-meter before soldering them to board.

3

Make sure you understand the polarities and orientations of all parts.

Important !!!

If your have purchased 15002K kit (SMD not pre-soldered) you must install all
SMD parts before mounting the through-hole parts. Please refer to the instructions
below for SMD part installation. Otherwise, proceed to page2 to start through-hole
part assembly.

SMD parts are only installed to the analog board (PCB PN# 109-15001-xxx).

How to Solder SMD Parts

1. Before soldering check components against the
part list to make sure you have correct parts.

2. Identify IC orientation and diode polarity (see photos).

3. Do not put iron on one pad for too long time. Otherwise,
traces may peel off and get damaged.

If your kit does not have SMD
device pre-soldered you are
strongly suggested to install
all SMD parts before mounting
through-hole parts. Please see
instructions at Page 1.

Tools you need

1

20 - 25W iron for most of parts. For the
BNC connector higher power iron (50 ­100W) is recommended if available.

Soldering Hints

1

Put leads through mounting holes from the side with
part outline. Ensue component evenly touch PCB.

Solder leads at the other side. Solder should fully

2

fill and cover soldering pads.
Avoid bridges between
neighbering pads.

Cut unused leads

3

flush with cutter.

Step 1

Assembly the Main Board (follow the order as numbered)

1. Check the main board

Before mounting any parts to the main board

1

connect a 9V power supply (center positive) to J7
on the board to check the display.
You should see the scope boots up to a screen

2

similar to the photo below. D1 (LED) blinks twice.

Do not solder any parts to the board if you find
problem. Otherwise warranty will be voided.
Report the problem to vender or JYE Tech.

Let iron stay on one pad of the resistor until solder on

the other pad melt and then remove the part.
Note:
R30 is used to bypass SW5 so as the mainboard can be

tested without the power switch. It must be removed
for correct functioning of the power switch.

Now apply power again. Test power switch
and tact buttons for their correct functions.

If you have questions post them
to www.jyetech.com/forum.

About Trigger State

The trigger can have three states including Holdoff, Waiting, and Trigged. They are explained below.

Holdoff:
Waiting:
Trigged:

Trigger is disabled until a portion of sample buffer prior to a trigger point is filled with raw data.
Trigger is waiting for a valid signal slope.
A valid signal slope has been detected and registered.

Operations

Set Couple Switch to GND position. Hold down [V/DIV] button for about 3 seconds.

Hold down [OK] button for about 3 seconds. This will turn ON or OFF on-screen display of
measurements including Vmax, Vmin, Vavr, Vpp, Vrms, Freq., Cycle, Pulse width, and Duty cycle.

Press [ADJ] & [] buttons simultaneously. The currently displayed waveform
will be saved to EEPROM. The existing data in EEPROM will be over-written.

Press [] & [] buttons simultaneously. ADJTrigger Recalled waveform is always displayed

in Hold state.

Hold down [SEC/DIV] and [TRIGGER] buttons simultaneously for about 3 seconds.

Hold down [SEC/DIV] button for about 3 seconds. This will make the data at the center
of capture buffer displayed.

Hold down [TRIGGER] button for about 3 seconds. This will set the trigger level t0 the
medium value of signal amplitude.

Short press of [ADJ] toggles mode on and off for VPos, HPos, and
Trigger Level. A “ >>” sign appearing at top of screen indicates is ON.
