1. Introduction , Application and Features:Power Clamp meter is a Portable Digital multi functional measuring instrument .designed for Measuring selected power network parameters, AC/DC Voltage, AC/DC current, Resistance, Continuity, Diode and Frequency. Apart From basic quantities meter enables the measurement of additional quantities calculated from values of voltage and current.

Power clamp meter is innovatively designed for increasing safety and comfort of user. Rotating clamp jaws facilitate the measurement at physically awkward position, vertical bus bars , conductors placed at position difficult to access. Clamp jaws can be opened or closed with the triggered placed at bottom side placed away from the jaws . This allows the user to place his/her hand at safer distance from live conductor.

.Location and design of trigger eliminates fatigues caused by single finger operation. It allows spreading the force required to open the jaws over more than one finger to ensure comfortable operation.

Power Clamp meter have following features

2. Safety features and safety precautions

Please note the following safety precautions:

Power Clamp meter provides a very high degree of safety.The digital power clamp meterin compliance with the safety standard IEC 61010-1:2010.In case of incorrect use or careless handing,the safety of both user and power clamp meter is not assured.

For proper use and safe handling,it is absolutely necessary to read andunderstand the operating instructions before using the clamp meter.

400A/1000A manufactured and tested

The clamp meter must be operated only by persons who understandthe danger of shock hazards and are aware of the necessary safetyprecautions.Shock hazards exist wherever voltages of more than30V(TRMS) are present.Do not work alone in shock hazardous environment while carryingout measurement.

Operators must use individual protective equipment if hazardous live parts of installation could be accessible .Keep hands/fingers behind the edge that separates rotating jaws with hand held part(10). This is the limits of the hand held part during measurement.

The maximum permissible voltage between any of the terminalsockets (7) and ground is 1000V.

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

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
