Chapter 5 Various Functions
5.1 LOCK mode
It is the mode makes all keys unable. Use when you want
to fix one of the measurement displays (For all displays).
In this mode, you can not input by any keys.
When you press <SET> continuously for about 3sec., the
‘LOCK’ indicator lights and all keys become locked
(pressing them will have no effect).
Press <SET> continuously for about 3sec. again to
release Lock mode. The ‘LOCK’ indicator goes off and
the lock mode is released (unlocked).
5.2 Pulse output function
Refer to the mode 1 setting for the way to set.
‘OP.’ indicator is lighting when pulse output.
5.2.1 Output depends on integrated electric power
Set the unit for pulse output (0.001/0.01/0.1/1/10/100kWh) and pulse output (transistor output) turns on
every time when integrated electric power reaches the unit. (Pulse width: about 100ms)
5.2.2 Instantaneous electric power alarm
When it exceeds the setting instantaneous electric power, pulse output (transistor output) turns on in
order to notice. When it falls below, the output turns off.
5.2.3 Current alarm
When it exceeds the setting current ratio, pulse output (transistor output) turns on in order to notice.
When it falls below, the output turns off.
5.2.4 Stand-by power alarm
When it detects stand-by power (current) of the measured load, pulse output (transistor output) turns on
in order to notice.
Set current (C) and stand-by time (T) to judge stand-by power.
When the measured load is satisfied the setting conditions, pulse output
(transistor output) turns on in order to notice.
You can reset the alarm by pressing <SET> with the instantaneous electric
power display.

5.2.5 Output depends on count value
Set the preset value and pulse output (transistor output) turns on the time when count value reaches
the preset value.
5.2.6 Demand alarm
Refer to the next in detail.
5.2.7 Pulse-through
Pulse output (transistor output) turns on every time when a pulse is input.
*This function can be used with a pulse signal with pulse width 10ms or more.
*It doesn’t have a function of pulse converter.
