OSC ILLO SCO PE IN STRU CTI ON MA NUAL
WARN IN G
Normal use of test equipment exposes you to a certain amount of danger from electrical shock because testing must often be performed where exposed high voltage is present. An electrical shock causing 10 milliamps of current to pass through the heart will stop most human heartbeats. Voltage as low as 35 volts DC or AC rms should be considered dangerous and hazardous since it can produce a lethal current under certain conditions. Higher voltage poses an even greater threat because such voltage can more easily produce a lethal current. Your normal work habits should include all accepted practices that will prevent contact with exposed high voltage, and that will steer current away from your heart in case of accidental contact with a high voltage. You will significantly reduce the risk factor if you know and observe the following safety precautions.
1. Don't expose high voltage needlessly in the equipment under test. Remove housings and covers only when necessary. Turn off equipment while making test connections in high-voltage circuits. Discharge high-voltage capacitors after removing power.
2. If possible, familiarize yourself with the equipment being tested and the location of its high voltage points. However, remember that high voltage may appear at unexpected points in defective equipment.
3. Use an insulated floor material or a large, insulated floor mat to stand on, and an insulated work surface on which to place equipment; make certain such surfaces are not damp or wet.
4. Use the time-proven "one hand in the pocket" technique while handling an
instrument probe. Be particularly careful to avoid contacting a nearby metal object that could provide a good ground return path.
5. When using a probe, touch only the insulated portion. Never touch the exposed tip portion.
6. When testing ac powered equipment, remember that ac line voltage is usually present on some power input circuits such as the on-off switch, fuses, power transformer, etc. any time the equipment is connected to an ac outlet, even if the equipment is turned off.

TES T INSTRU MENT SAFE TY
7. Some equipment with a two-wire ac power cord, including some with polarized power plugs, is the "hot chassis" type. This includes most recent television receivers and audio equipment. A plastic or wooden cabinet insulates the chassis to protect the customer. When the cabinet is removed for servicing, a serious shock hazard exists if the chassis is touched. Not only does this present a dangerous shock hazard, but damage to test instruments or the equipment under test may result from connecting the ground lead of most test instruments (including this oscilloscope) to a "hot chassis". To make measurements in "hot chassis" equipment, always connect an isolation transformer between the ac outlet and the equipment under test. To be on the safe side, treat all two wire ac powered equipment as "hot chassis" unless you are sure it has an isolated chassis or an earth ground chassis.
8. Never work alone. Someone should be nearby to render aid if necessary. Training in CPR (cardio-pulmonary resuscitation) first aid is highly recommended.
9. Equipment limited for use in CS AND RS controlled environmental conditions.

DESCRIPTION
The model PS-XX0/XX1/XX5 oscilloscope is a dual-channel oscilloscope with
frequency bandwidth 20~100 MHz at -3dB; maximum sweep 10 nS/DIV; maximum sensitivity 1 mV/DIV and 150 mm rectangular CRT with internal graticule.
The oscilloscope is rugged, easy to operate and highly reliable. It also provide many convenient feature and special functions which make itself be an special for research, production , education, and development in electronic device or circuitry.
FEATURES
(1) Ease of Operation
All control and function switches are laid out in the most convenient locations
making the oscilloscope extremely easy to operate.
(2) High Input Impedance
The input impedance of CH 1, CH 2 IS 1MΩ ±2%, 25 pF ±10pF.
(3) Variable Hold Off Function
Signals with complex repeating periods which resist triggering can be stably
triggered with a simple adjustment of the hold off level.
(4) X-Y Operation
CH 1 can be applied as horizontal deflection (X-axis) while CH 2 provides vertical
deflection (Y-axis).
(5) Trigger l of TV Sync
The oscilloscope has a sync separator circuit, which allows triggering for TV-H and
TV-V signal.
(6) High Sensitivity
1 mV/DIV maximum vertical sensitivity. 10 nS/DIV maximum sweep rate.
(7) Sweep Mix Function (PS-XX5 only)
The main sweep and the delay sweep can be viewed at the same time.
(8) CH 2 Output (PS-XX5 only)
CH 2 output which on near panel can be connected to frequency counters and other
modulation signal.

GEN ERAL
(9) Z Modulation (PS-XX5 only)
Input terminal is used for external intensity modulation signal.
(10) Component Test (PS-XX1/XX5)
Capacitor, indicator, diode, transistor and zener can be also viewed on screen.
(11) Beam Finder (PS-XX1/XX5)
Trace can be returned to CRT viewing area regardless of setting horizontal, vertical
or intensity controls when press beam finder button.
(12) Illumination Control (PS-xx1/xx5)
Graticule illumination can be adjusted according to brightness of circumstance.
