The Normal day rate is R1 and the nighttime Low rate is R4.
What does R1 mean on electric meter?
Day reading
R1 is your Day reading, and R2 is your Night reading. Write down the numbers on the screen from right to left, including any zeros, and ignoring any numbers after the decimal point.
Why do I have 2 electric meter readings?
If you get cheaper electricity at certain times, you might have a two rate (or ‘dual-rate’) meter. This means it will have 2 rows of numbers. The top row (labelled ‘low’ or ‘night’) shows how many units of cheaper electricity you’ve used.Ignore any numbers shown in red.
How do I read my digital electric meter?
When reading an electric meter, read and write down the numbers as shown on the dials from right to left. When the pointer is directly on a number, look at the dial to the right. If it has passed zero, use the next higher number. If it has not passed zero, use the lower number.
What is R1 and R2 in electricity?
R1 = resistance of phase conductor ie Live. R2 = resistance of cpc ie earth. Cheers Paul. Just a minor correction, the Zs of an Electrical Installation is the impedance of the entire system, that is from transformer to socket outlet or final circuit.
What does R4 mean on electric meter?
The Normal day rate is R1 and the nighttime Low rate is R4.
Is Rate 1 Night or Day?
In this example, you can see that Rate 1 has advanced 20 kWh during the hours of 9am to 5pm, therefore we can confidently say that Rate 1 relates to the Day and Rate 2 is the Night.
What do the numbers on a digital electric meter mean?
Digital electric meters have numeric displays that show numbers in kilowatt hours. A kilowatt is equal to 1,000 watts. If you have a 100-watt light bulb that is turned on for one hour, then 100 watt hours or 0.1 kilowatt hours is consumed.
Why is my gas reading so high?
High gas bills may be due to a gas meter that is incorrectly recording the amount of gas you are using, but this is unusual. While there is no simple way you can test whether your meter is accurate, if you are concerned about your meter readings, contact your energy supplier.
How do you calculate meter reading?
Energy charge: Suppose current month unit is 300 unit and previous month unit is 500 unit. That is total= 605+685= 1290 (It is the unit charge of 200 unit for 30 days).
How do I know if my electric meter is correct?
If you have a credit meter
- If the meter stops, turn on 1 appliance at a time and check the meter.
- If the meter is still moving, it’s probably faulty.
- If it’s faulty, your supplier should replace it.
- If it’s not faulty, you could have to pay for the cost of the test.
How much is 1 kWh in the Philippines?
Average electricity rate per kilowatt hour of Meralco Philippines 2019-2020. In 2020, Meralco in the Philippines had an average retail electricity rate of 7.96 Philippine pesos per kilowatt hour. This reflects a 10 percent decrease from the previous year’s average retail rate.
How do I read my electricity meter in South Africa?
Dial or clock face electricity meters record the amount of electricity used in your home kWh. The record is cumulative. Read the dials from left to right, ignoring the dial marked 1/10 as it is only for testing. Each dial revolves in a different direction from the one next to it, eg anti-clockwise, then clockwise.
What is an acceptable R1 R2 reading?
The R1 + R2 reading when the dimmer is bypassed, is a reasonable 1.7 ohms, which is protected by a 6A Type B circuit breaker.If your client intends to continue to use the dimmer switch, it may be acceptable to fit a suitably rated RCD to provide automatic disconnection.
What is R1 and R2 testing?
For each outlet on a circuit, the resistance of both the live and earth conductors together (R1+R2) is measured back to the source.This test is usually repeated for the resistance of both the live and neutral conductors together (R1+Rn), although the result is generally not recorded on testing forms.
What is the maximum R1 R2?
I would expect an r1 not to exceed 0.73, r2 not to exceed 1.20 and an R1+R2 not to exceed 0.48, disregarding spurs for this example.

What is R2 reading?
R2 readings generally confirm the presence of an earth.. Zs readings will then confirm that disconnection times are met… Zs can be calculated or taken as a reading, this will give you R1 if you know R2 and Ze… but if you cant do either you cant state it…
Is r1 R2 a dead Test?
Test method 1 will yield (R1+R2) for the circuit whilst test method 2 will yield the R2 value. This is a Dead Test so Safe Isolation is Required Involves ensuring cpc is continuous and connected to each outlet, there are no interconnections, and to verify polarity.
If your meter has an ‘A’ and ‘B’ button, press ‘A’ until you get to TOTAL ACT IMPORT. The number below this is your electricity reading. Your meter might have three buttons to the side of the display. If this is the case, just press the middle button, and the display will show your reading below the ‘IMP’ on screen.
If your meter has A and B buttons under the screen
press the A button again until you see ‘METER INDEX’ and numbers followed by ‘M3’ write down the number from left to right. ignore any zeroes at the beginning and any numbers after the decimal point.
Why does my electric meter have 3 readings?
Your meter may show you 3 readings – one will be your day reading, one your night reading and the final reading is a total reading. We’ll only need to take the day and night readings.
