1) 1st display
Displays the measurement value or type of setting data.
2) 2nd display
Displays the unit or the parameter name of the measurement data or setting data.
3) Operation display
・OUT1: The light turns ON in conjunction with the output set to the OUT1 terminal.
・STOP: Lights ON when power is supplied after the time measurement function stops
following back-up power failure during power OFF. Lights OFF by setting time data.
When using the product with lights ON, measurement data log cannot be recorded.
・
(Key): Lights ON at protect setting.
4) Temperature unit
When selecting Celsius in the temperature unit setting, is shown.
°C
When choosing Fahrenheit, °F is shown.

Basic usage

Setting Examples
Applicable circuit type: 1-phase 3-wire
Dedicated CT type: 5ACT
Time: March 5, 2010, 17:15
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).
B. Set applicable circuit type to 1-phase 3-wire.
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.
D. Set the time to March 5, 2010, 17:15.
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.
