If the rotary is not set at the 3f function, the button is used as
a READ button.
If users ever store data in the memory by:pressing REC button,
pressing the READ button will retrieve the data from the memory.
First the data number will be shown in LCD, then the data stored.
Once READ function is enabled, symbol of REC and NO. will be
shown in LCD to indicate the power clamp is in READ mode. The
reading shown in LCD is not current reading but data stored in
memory. To exit READ function. turn the rotary switch to change
funclion.
9. V input Terminal
This terminal is used as input for voltage measurements.
10. COM Terminal
This terminai is used as common reference input.
11. DC A/W ZERO button
When users find the reading of A or W is not zero, press this
button once will zero the A or W reading (Users do not need
to press and hold the button). When the power clamp is doing
the zero action, a symbol of ZERO will be shown in LCD.

1. Transformer Jaw
This is used to pick up current signal. To measure AC+DC
current or AC+DC power, conductor must be endosed by the
jaw.
2. Transformer Trigger
This is used to open the jaw.
3. Data Hold Button
Once this button is pressed, reading will be held in the LCD.
Press again to release it.
4. Function Selection and On/Off Switch
This is used to sealed the function users desired, such as
KW, V, A, Phase, KVA or 3f.
5. LCD
This is a 4 digits Liquid Crystal Display with maximum
indication of 9999. Function symbols, units, sign, decimal
points, low battery symbol and zero symbol are included.
6. Units Symbols
Once a function is selected, corresponding unit (KW, V, A,
Phase, KVA, or 3f) will be displayed in LCD.
7. 3f f f f f 3W and 3f f f f f 4W Select Button (3 wire or 4 wire systems)
If the 3f system is not a balanced system, users can press
this button to select between 3f3W, 3f4W or a balanced
system. Once pressed, LCD will show symbol of 3f3W or
3f4W depends on the function selected.
8. Read/Next Button
When the rotary switch is set at 3f function, the button is
used as a NEXT button In the 3f balanced system mode,
pressing the NEXT button will enable users to select W+PF,
KVA+KVAR or V+A to be displayed.
In the 3f3W system mode, Pressing the NEXT button to
12. REC button
The clamp meter can store 4 data in memory. Once the
button is pressed, the data number will be shown in LCD.
A REC symbol will be shown in LCD if any data is stored.
If the memory is full, FULL will be show in LCD. To clear
memory, users need to turn the power off and on again.
13. Low Battery Symbol
When this symbol appears, it means the battery voltage
drops below the minimum required voltage. Refer to Section
V for battery replacement.
14. REC and NO. symbols
If users observe REC is shown that means data is stored in
memory. If users observe both REC and NO. are shown,
that means readings shown in LCD are data stored in memory
not current data measured.
Test equipment risk assessment (UK recommendation)
Users of this equipment and/or their employers are reminded
that health and safety legislation requires them to carry out
valid risk assessments of all electrical work so as to identify
potential sources of elctrical danger and risk of elctrical
injury such as from inadvertent short circuits. Where
assessments show that the risk is significant than the use
of fused test leads constructed in accordance with the HSE
note GS38 "Electrical Test Equipment for use by
Electricians" should be used.
