Shiva Amvaj Ampere meter 96
Ampere meter 96 (single phase) has a large display indicator that is capable of measuring and displaying crossing current from 0.01A to 6000A in different CT ranges .This device is equipped with a maximum current recording system(Maximeter). Current is measured in NORMAL and TRUE RMS methods.

How to select and adjust intended CT
After connecting electricity to the device and choosing intended CT and relating it to considered terminals, CT is adjusted as follows :
By pressing SELECT key, CT&SETTING LED starts blinking. Choose intended CT range by pressing RESET MAX-A SETTING CT and repress SELECT key in order to enter accurate CT adjustmen stage .
In this stage it can be possible to change CT value in order to correct probable CT fault and increase its accuracy to ±۲۵ times the current measurement unit. Press SELECT key to exit the program.
Example: if intended CT sets to 5, in accurate adjustment stage the CT value can be altered to ±۲۵ times 0.01 (current measurement accuracy)which equals to ±۰٫۲۵ . It means CT value is changeable from 4.75 to 5.25.
Note 1: our purpose of unit is current measurement accuracy in different ranges.
Note 2: CT adjustment is possible just at the first 5 minutes when power connects. If it is needed to change and replace CT range , disconnect and reconnect input power and re-do adjustments.
Normally after CT adjustment A indicator placed on device turns on and displays current crossing the CT accurately. Current calculation method can be changed from NORMAL to TRUE RMS by pressing SELECT key.
Maximum registered current is seen by pressing SELECT key and MAX-A indicator is turned ON.
In this situation(maximum display), by pressing and holding RESET MAX-A SETTING CT a countdown starts from 5 to 1. Upon reaching zero maximum current sets to zero.
Note 3: if the key is released before finishing countdown, the maximum registered current won’t be zero and this operation must be re-done.
Note 4: a current would be registered as a maximum current which lasts at least 15 seconds.
