Year, month/day, and hour/minute should be set
continuously. If it was canceled in process, all
values will return to previous values. As soon as
setting hour and minute, the settings are reflected.
Set the moving average time of the Moving
average Current.
Cancel it during the input or set a value out of the
range, come back before a change.
Initialization

A. After checking the wiring, turn ON the power supply.
“
Hm50c
” is displayed and EEPROM is read (“
wait
” is displayed for 16 sec max).
When the power is turned ON for the first time, “
e-t1
” is displayed and STOP
turns ON because time has not been set. 3 sec
later, active power in measure-
ment mode is displayed. (STOP remains ON).
1. Press the
M
key for more than 3 sec to go to applicable circuit type “
00.typ
”
in operation setting mode.
2. Press the
U
key to shift to setting state. Press the
U
key to change the
applicable circuit type from “
3p3w
” to “
1p3w
”, and then press the
O
key to confirm.
C. Set dedicated CT type to 5ACT.
1. Press the
S
key to move to dedicated CT type “
01.c.rg
”.
2. Press the
U
key to shift to setting state. Press the
U
key to change the
dedicated CT type from “
100a
” to “
5a
”, and then press the
O
key.
To use the log function, time setting is required.
1. Press the
S
key to move to time setting “
11.tim
”.
2. Press the
U
key to shift to setting state.
Check that the year is "
2010
”, and then press the
O
key.
3. Change the value of Month/Date with the
U
key and shift the digit with the
S
key to change the value from “
01 01
” to “
03 05
”, and then press the
O
key.
4. Change the value of Hour-Minute with the
U
key and shift the digit with the
S
key to change the value from “
00-00
” to “
17-15
”, and then press the
O
key.
The content of the time setting will be saved and STOP will be turned OFF.
5. Press the
M
key for more than 3 sec to move to measurement mode
(measurement start). When you move to measurement mode, the setting will
be saved and “
save
” is displayed.
This completes the basic settings.
