In order to do the Step Method for PickUp/Pull In Voltage measurement of Relays. Also I want to generate one pulse at a time by manual control. I am using 28V relays, so that I have to increase the step voltage from 0-20V in 0.5V steps. And manual stepping is required since when the relay...
Help me to design a Monoshot with the following specifications
1. 200ms pulse width
2. Magnitude 0.5V steps in 0-20V range (total 40 pulses). That is 0,0.5V, 1V, 1.5V,......,19.5V & 20V.
3. capacity to drive maximum 1A load.
We are using MIL standard Latching Electro-mechanical relays having dual ON/OFF coils. During screening process the relays are being subjected to pull-in voltage
measurements for both ON & OFF coils in SRC (25 degree Celsius),COLD (8 degree Celsius) & HOT (80 degree Celsius) conditions. For...
What you mean by 'measure an electric field' ? Is it ac voltage at floating terminal ?
- - - Updated - - -
Here is my interpretation considering the case of non-ideal diode,
CASE 1(without 10K)-- Depending on the output impedance of DC voltage source and the input impedance of the MM, the...
Consider the circuit arrangement shown in the attachment.
If I connect a MM in voltmeter mode at floating terminal A, What would be the reading on the voltmeter?
If I terminate the floating A terminal with a 10K resistor to GND, What would be the change in reading shown?
See the diagram attached herewith.
What would the mulmeter shows if I connect a multimeter accross
A & B in resistance mode ?
DFR-Diode Forward Resistane
DRR- Diode Reverse Resitance
Both are identical diodes and the multimeter is set in auto range.
For the below circuit, I have placed multimeter +ve probe at 'B' wrt GND and measures 4V against the expected value of 0V.
Hence I have terminated the 'B' end with 10K to GND temporarily before taking the measurement and reads 0V.
Why this happens?
What happens to the anode of D2 while I...
Consider the below circuit with 28V supply and electronic load set at 5A Constant Current mode.
What voltage drop would I expect when I connect a digital multimeter between A & B ?
V(AB1)= V(R6)+V(R8)+V(R9)
What voltage drop would I expect when I connect a digital multimeter between C & D ...
Resistance/Voltage measurement using multimeter
Consider the below circuit with 28V supply and 5A load.
What voltage would I expect when I connect a multimeter between A & B ?
V(AB1)= V(R6)+V(R8)+V(R9)
What voltage would I expect when I connect a multimeter between C & D ?
V(CD1)=...
I have designed oneshot for 1ms Pulse width using 4047.
R5- makes output current >= 10mA to ensure load regulation.
C4- prevents bouncing of trigger switch.
1N4002- prevents discharging of c1 through LM317T.
1. Is it possible to see the 1ms 'short time' switching between RED & GREEN LEDs at...
I dont want to connect a capacitor across a switch directly as the switch shorts out the cap when it is closed. That's not that good of an idea. However, with a small resistor like 100 ohms in series with the cap, all is well.
If I connect 100 Ohm in series with the capacitor across the switch...
