|
| Slide Number 7
Fields
|
Device can be used in fields such as:
|
| Let's begin with terminals on the top Panel. | |
| Point to ground(GND) terminals. | Panel has four ground (GND) terminals.
At these terminals the voltage is zero volt(0V). Voltage measured at other input terminals, is with reference to ground(GND) terminals. |
| Point to terminals A1 and A2 | Input terminals A1 and A2 can measure voltage between -5V to +5V. |
| Point to terminal IN1 and IN2. | On the left, IN1 and IN2 terminals can measure voltage between 0 to 5V.
'IN1 also measures capacitance up to 5000pF(pico farads), with good accuracy. |
| Point to PVS | PVS is Programmable voltage source.
It is used to deliver voltages in 0-5V range with a minimum step of 1.25mV(milli volts)and can deliver up to 5mA(milli amps). |
| Point to SINE | SINE delivers a constant frequency around 150 Hz,at an amplitude around 4volts. |
| Point t to SEN | SEN is mainly used for connective sensor elements like photo-transistors, Light Dependent Resistors, Thermistors etc.
It is a voltage measuring terminal with an internal 5.1k resistor connected to 5 volts. |
| Point to SQR1 and SQR2 terminals | SQR1 and SQR2 terminals can generate Square waves of “0” to “5V” with a frequency from 0.7 Hertz to 100 Kilo Hertz. |
| Point to OD1 | OD1 produces a digital output as 0V or 5V, under Software control. |
| Point to MIC | MIC captures sound from an external sound source. |
| Point to CCS | CCS means Constant Current Source.
It gives 1mA(one milli Amps) current with a load resistor of 3kΩ(kilo ohms), since voltage should be kept below 4 volts. |
| Point to IN->OUT | Inverting amplifier (IN->OUT) is used to amplify external voltages.
It may be used to amplify external condenser or mic output. |
| Along with the device, some accessories are provided. | |
| Point to all the accessories one by one. | Accessories list include:

| Point to msec/div (milli second per division) | msec/div(milli second/division) represents time axis. |
| Point to Volt/div | Volt/div represents volt axis. |
| Point to Trig level | Trig level is a trigger controller. |
| Point To DEL.
Click on CH2 and drag to DEL. |
Click on CH2 and drag to DEL.
It removes CH2. |
| Point to DEL.
Click on CH1 and drag to DEL. |
Click on CH1 and drag to DEL.
It disables the display of CH1. |
| Point to FTR. | FTR generates Fourier spectrum of the wave. |
| Point to Setting Squarewaves | Under Setting Squarewaves we have a number of input and check boxes. |
| Point to Frequency input box. | In this input box we can change the Frequency of the wave in Hertz, |
| Point to phase difference input box. | This is to change phase difference, dphi in percentage(%). |
| Point to Set PVS= | In Set PVS= input box we can enter the desired voltage value between 0 to 5V.
Press enter to set the value. |
| Point to the check boxes, SQR1, SQR2 and BOTH. Point to the slider. | SQR1, SQR2 and BOTH check boxes are used to activate the frequency.
Frequency can be changed using the slider. |
