3.16. Reading Data in Memory

To retrieve data in memory, press the READ button as long
as rotary switch is not set at 3ffunction.
Once the read button is pressed, the record number will be
first displayed. then data is displayed after. Once in the READ
function, the REC. NO. symbols will be displayed in LCD.
To exit the READ function, turn the rotary switch to change
function.
NOTE:
If users observe both REC and NO. symbols are shown in LCD,
users should know that the readings shown in LCD are not cur-
rent data measured. They are data stored in the memory.

NOTE :
The indication of phase sequence is not limited to 3f balanced
power. It can be used in general as long as the PF displayed is
greater than 0.1.
Set the power clamp In 3f balanced power mode, the power
clamp will automatically detect phase.
3.14.1. Set the rotary at 3f.
3.14.2. Connect the voltage input (red terminal) to R (or L1)
phase, connect the COM input (black terminal) to S
(or L2) phase, and clamp on the T (or L3) phase. When
clamp on the T (or L3) phase, the power clamp must
face the power source.
3.14.3. If the phase sequence is clockwise, R, S, T sequence
will be shown and flashed. (refer to figure 17 )
3.14.4. If the phase sequence is counterdockwise, T, S,
R sequence will be shown and flashed. (refer to
figure 17)
3.14.5. If the current signal (where jaws clamp on) is not
detected, only one of the R, S or T will be left in LCD.
NOTE :
The "+" sign printed on jaw must face the power source for correct
measurement.

3.15. Recording Data in Volatile Memory

The power clamp can store 4 data in its own memory. To
store any data displayed in LCD, press the REC button. If
the power clamp has stored 4 data already, LCD will display
FULL. The data is lost if power is turned off.
The REC symbol will be displayed in LCD if any data is
stored.
NOTE :
If users observe REC (only) is shown in LCD, that means some
data is stored in memory.
