OpenScope 2C53T - Button & Navigation Manual

Physical buttons: MENU, AUTO, SAVE, CH1, CH2, PRM, SELECT, UP, DOWN, LEFT, RIGHT, OK, MOVE

Emulator keys: M=MENU, A=AUTO, S=SAVE, 1=CH1, 2=CH2, P=PRM, Space=SELECT, Arrows, Enter=OK

Mode Switching

The device has 4 modes, cycled by pressing MENU:

Oscilloscope  -->  Multimeter  -->  Signal Generator  -->  Settings
      ^                                                       |
      +-------------------------------------------------------+

If you're inside a Settings sub-menu, MENU goes back to the top-level Settings list first, then cycles to Oscilloscope on the next press.

Oscilloscope Mode

Channel Controls

Button Action
CH1 Select CH1 as active channel + cycle coupling (DC -> AC -> GND)
CH2 Select CH2 as active channel + cycle coupling (DC -> AC -> GND)
SELECT Cycle probe setting (1X -> 10X) for active channel

Vertical / Horizontal

Button Action
UP Increase V/div for active channel (zoom out vertically)
DOWN Decrease V/div for active channel (zoom in vertically)
LEFT Decrease timebase (faster sweep, zoom in horizontally)
RIGHT Increase timebase (slower sweep, zoom out horizontally)

V/div steps: 5mV, 10mV, 20mV, 50mV, 100mV, 200mV, 500mV, 1V, 2V, 5V

Timebase steps: 5ns, 10ns, 20ns, 50ns, 100ns, 200ns, 500ns, 1us, 2us, 5us, 10us, 20us, 50us, 100us, 200us, 500us, 1ms, 2ms, 5ms, 10ms, 20ms

Trigger

Button Action
MOVE Cycle trigger edge (Rising -> Falling)
OK Toggle Run / Stop

Cursors

Button Action
TRIGGER Cycle cursor mode: Off -> Vertical -> Horizontal -> Both -> Off
UP/DOWN Move active cursor
LEFT/RIGHT Switch between cursor pairs (V1/V2 or H1/H2)

When cursors are active, UP/DOWN/LEFT/RIGHT control cursors instead of V/div and timebase. The cursor readout shows delta-time (dt), frequency (1/dt), and delta-voltage (dV).

FFT / Spectrum Views

Button Action
PRM Cycle view: Time -> FFT -> Split -> Waterfall -> Time
SELECT Cycle FFT window function (in FFT/Split/Waterfall views)
UP/DOWN Adjust reference level (+/- 5dB, in FFT views)
LEFT/RIGHT Zoom in/out frequency range (in FFT views)
AUTO Auto-configure FFT (generate test signal + optimize)

Note: Entering an FFT view claims the shared memory pool (88KB). Returning to time view releases it.

Run Control

Button Action
OK Toggle acquisition Run / Stop (shows popup)

Multimeter Mode

Sub-mode Navigation

Button Action
LEFT Previous meter sub-mode
RIGHT Next meter sub-mode
OK Cycle layout: Full -> Chart -> Stats -> Full
AUTO Toggle relative/delta mode (REL) — zeros at current reading, shows deviation
TRIGGER Toggle auto-hold (HOLD) — freezes display when reading stabilizes
SELECT Reset min/max/avg tracking (also resets chart and histogram)

10 Sub-modes

0: DC Voltage       5: AC Current (A)
1: AC Voltage       6: Resistance
2: DC Current (mA)  7: Continuity
3: DC Current (A)   8: Diode Test
4: AC Current (mA)  9: Capacitance

3 Display Layouts

  • Full — Large digits, bar graph, min/max/avg, range info. Classic DMM.
  • Chart — Compact reading on top, scrolling strip chart below with auto-scaling Y axis. Shows measurement trend over time.
  • Stats — Compact reading, min/max/avg/peak-to-peak statistics, and histogram of reading distribution.

Signal Generator Mode

Waveform & Output

Button Action
SELECT Cycle waveform type
OK Toggle output ON / OFF

Waveforms

Sine -> Square -> Triangle -> Sawtooth -> Full-Rect Sine -> Half-Rect Sine -> Pulse -> Noise

Parameters

Button Action
UP Increase amplitude (+0.1 Vpp)
DOWN Decrease amplitude (-0.1 Vpp)
LEFT Decrease duty cycle (-5%)
RIGHT Increase duty cycle (+5%)
PRM Cycle frequency presets: 1 -> 10 -> 100 -> 1k -> 10k -> 25k -> 1 Hz

Settings Mode

Top-Level Menu (9 items)

> Oscilloscope Settings    [sub-menu]
  Sound and Light
  Auto Shutdown

Navigation

Button Action
UP Move selection up
DOWN Move selection down
OK Enter sub-menu or toggle selected option
MENU Back to top-level (from sub-menu) or cycle to Oscilloscope mode

Display Mode (OK to cycle)

Dark Blue -> Classic Green -> High Contrast -> Night Red -> Dark Blue

Oscilloscope Settings Sub-menu (depth 1)

> CH1 Coupling      [DC / AC / GND]
  CH1 Probe         [1X / 10X]
  CH1 20M Limit     [ON / OFF]
  CH2 Coupling      [DC / AC / GND]
  CH2 Probe         [1X / 10X]
  CH2 20M Limit     [ON / OFF]
  Trigger Mode      [Auto / Normal / Single]
  Trigger Edge      [Rising / Falling]

Press OK on any item to cycle its value. MENU to go back.

Math / Persist Sub-menu (depth 3)

> Math Channel      [Off / A+B / A-B / A*B / A/B / Max / Min]
  Persistence       [On / Off]
  Back
  • Math Channel: OK cycles through math operations, then back to Off
  • Persistence: OK toggles on/off. Enabling persistence claims the shared memory pool (evicts FFT if active)

Component Tester (depth 4)

Button Action
SELECT Cycle component type
OK Enter Resistor Calculator

Resistor Color Band Calculator (depth 5)

Interactive graphical resistor with 4 color bands (Digit 1, Digit 2, Multiplier, Tolerance).

Button Action
LEFT/RIGHT Move between bands
UP/DOWN Change selected band's color
SELECT Simulate measurement and show pass/fail
OK Back to Component Tester

Calculates expected resistance from color bands, then compares against measured value showing deviation percentage and PASS/FAIL against the selected tolerance.

About Screen (depth 2)

Shows device info, pool status, heap free, license. MENU or OK to go back.
