In DC mode, select from the following:
CYC-50/60Hz
Select this option to measure DC output
inverter welding current in units of cycle.
Set the frequency of the current you wish
to pass in FREQUENCY in the SETUP (1)
screen.
(50 Hz: 100 CYC, 60 Hz: 120 CYC)
ms
Select this option to measure DC output
inverter welding current in units of ms.
Measurement time: 2,000 ms max.
ms-SHORT
Select this option to measure transistor
welding current.
The current flow time is 1ms when ms is
selected. In contrast, the current flow time
is every 0.05ms when ms-SHORT is
selected, thus allowing measurement at
more frequent intervals.
Measurement time: 100 ms max.
When you have selected ms-SHORT, you
cannot measure force, external
±
10V
voltage input or displacement.

depending on the COIL TYPE setting in the
STATUS (1) screen:
COIL GAIN 1
2.000kA / 6.00kA /
20.00kA / 60.0kA /
200.0kA
COIL GAIN 10

(VOLTAGE
RANGE)
Select from the following two ranges:
6.00 V / 20.0 V
*1:
Force when FORCE is selected, and external
±
10V voltage input when External
(EXTERNAL) is selected, for Measurement Selection (SELECT MEAS) in the
STATUS (1) screen.
*2:
Only when FORCE is selected for Measurement Selection (SELECT MEAS) in
the STATUS (1) screen.
*3:
Only when External (EXTERNAL) is selected for Measurement Selection
(SELECT MEAS) in the STATUS (1) screen.
