Unique design for safety and comfortRotary mechanism for clamp jaws:
In conventional clamp meters display, keys and clamp jaws are in the same plane.When current measurement is to be done on vertical bus bars, over head cables,cables in congested places user connect the clamp meter but the keys and displaymay not be visible, hence not able to take the readings or operate the keys.
To over come the above mentioned problem has aunique feature called“Rotary mechanism for clamp jaws”. In this, the clamp jawsare rotating. Hence it is possible to align the clamp jaws as the orientation ofbus bar/conductor while keeping Display and keys facing the user, so that user cantake the readings and operate the keys.
Rotary clamp jaws can be rotated at different angles with the maximumup to 90 in both clock-wise as well as anti-clock wise direction as shown in

For example :-kVA reading.
V = 230V, I = 102A and Angle = 0 then kVA = 230*102 = 23.46 kVAkW = 230*102 * COS 0 = 23.46 kW and kVAr = 230*102*SIN 0 = 0 kVAr So Meter will display power like 23.46 kW, 00.00 kVAr, 23.46 kVA
Now Meter will display kW like 8.02 and not 8.023 as kVA is in 99.99 range.
With same V & I now if Angle = 70 then,kW = 230*102 * COS70 = 8.023kW and kVAr = 230*102*SIN70=22.04 kVAr
Meter will select range of all powers i.e. kW, hp and kVAr based on

Application
RISH Clamp 1000A measures important electrical parameters like AC Current, DC Current, AC Voltage, and DC Voltage. It also features Capacitance, Ohm & Continuity, frequency, and Duty cycle and temperature measurement.
Product Features
Unique DesignRish Clamp 1000A is a highly innovative design for features those increases safety and comfort of user. Rotating clamp jaws facilitate the measurement at physically awkward positions, vertical bus bars, conductors placed at positions difficult to access. Clamp jaws can be opened or closed with the trigger placed at bottom side away from the jaws. This allows the user to place his/her hand at safer distance from live conductor. This greatly reduces exposure of human beings to electrical shocks Location and design of trigger eliminates fatigues caused by single finger operation. It allows spreading the force r e q u i r e d to open the jaws over more than one finger to ensure comfortable operation. Comfortable operation of push buttons and function selector switch, in adverse field conditions.

RISH Clamp 1000A /300A measures important electrical parameters like AC Current, AC Voltage, DC Voltage. It also features Capacitance, Ohm & Continuity, frequency, Dutycycle and temperature measurement.
Rish clamp 1000A / 300Ais a highly innovative design for features those increases safety and comfort of user.nRotating clamp jaws facilitate the measurement at physically
awkward positions, vertical bus bars, conductors placed at positions difficult to access.
nClamp jaws can be opened or closed with the trigger placed at bottom side away from the jaws. This allows the user to place his/her hand at safer distance from live conductor. This greatly reduces exposure of human beings to electrical shocks
nLocation and design of trigger eliminates fatigues caused by single finger operation. It allows spreading the force requi red to open the jaws over more than one finger to ensure comfortable operation.
nComfortable operation of push buttons and function selector switch, in adverse field conditions.
Rish Clamp 1000A: Jaw opening of 55mm for standerd wire diameter of 50mmRish 300A : Jaw opening of 44mm for standerd wire diameter of 40mm
Narrow housing for firm grip and easy to carry.
The clamp meter can measure accurately at not only the High currents but also Low current ranges.
It is possible to conduct measurement using the clamp meter during night time in darkness with the help of Backlit. The back lit can be switched ON or OFF by pressing a single key.
Temperatures from -200 to 800 °C using Pt 100 and Pt 1000 sensors.
In order to save the power of the Batteries, the clamp meter will automatically shut OFF if it detects no activity for 10 minutes.
Analog scale that updates at the rate 20 times/sec to observe fluctuations in input.
In this mode, AUTO POWER OFF is disabled.
By pressing DATA HOLD button, reading on the display can be latched for Hands free operation.
By pressing MIN/MAX button, the clamp meter will start recording latest Minimum and Maximum readings
