1. Instruction

UT-CS09A/UT-CS09D is a stable, safe and reliable 3000A AC Rogowski flex Clamp Current Sensor

(hereinafter called current sensor). The core of the design is the Rogowski coil.

Warning:

To avoid electric shock or injury, please read Safety Instructions and Warnings before operating this

product.

2. Open Box Inspection

Open the package box and take out the device. Please check whether the following items are deficient

or damaged and contact your supplier immediately if they are.

BNC adapter------------------------ 1 pc

Battery: 1.5V AAA----------------- 3 pc

3. Safety Instructions

In this manual, a Warning identifies conditions and actions that pose hazard(s) to the user or the

test device.

This device strictly follows CE standards: IEC61010-1; IEC61010-031; IEC61010-2-032 as well as

CAT IV 600V, RoHS, pollution grade II, and double insulation standards.

If the clamp is used in a manner that is not specified in this manual, the protection provided by the

device might be impaired.

1) Do not use the device if the rear cover or the battery cover is not covered up.

2) When measuring, keep fingers behind the finger guard on the measuring head. Do not touch

bare cables, connectors, unoccupied input terminals or circuit being measured.

3) Before measuring, the switch should be on correct position. Do not switch positions during

measurement.

4) Do not use the clamp on any conductor with voltages higher than DC 1000V or AC 750V.

5) Use caution when working with voltages above 33V AC rms. Such voltages pose shock hazard.

6) Do not use the device to measure current higher than specified range. If current value being

measured is unknown, select 3000A position and reduce accordingly.

7) To avoid false reading, replace the battery if “POWER” indicator flashes. Remove the battery

if the sensor is left unused for a long time.

8) Do not change the internal circuit of the device.

9) Do not store or use the sensor in high temperature, high humidity, explosive, or strong magnetic

field environments.

10) Use soft cloth to clean the case, do not use abradants or solvents.

11) Do not use when the jaw or "jaw end" is worn.

7. Voltage signal output terminal

The corresponding voltage output of AC current measured through flexible current sensor.

6.Operations

BNC terminal can be used to connect flexible current sensor to read out on oscilloscope

Warnings：

To avoid false reading, do not use low input impedance settings when using oscilloscopes as readouts.

AC measurement

Warning:

Before measuring, switch off the conductor to be measured. Do not turn on the conductor before the sensor

is locked around the conductor to be measured.

Caution:

Keep your hands away from the Rogowski ring and conductor to be measured.

1.Connect the sensor with alternating voltage measure device e.g. multimeter. (see figure 2)
