Basic Operation
3.1 Changing the Response Setting
To enable stable measurements in the low frequency range, there are two
response settings available.
FAST (response time: 0.2 to 0.3 seconds)
This allows stable measurement for a constant input of at least 45 Hz, but at
frequencies below 45 Hz the measured value fluctuates. When power
transients or fluctuations occur, they are followed.
SLOW (response time: 5 to 15 seconds)
This allows stable measurement down to 1 Hz, but sudden fluctuations
cannot be followed.
Pressing the
RESPONSE
keys changes display as follows.
With the AUTO selection, the response setting is switched in the following
conditions.
1. The FAST response is used when the frequency is 45 Hz or above, and the
SLOW response otherwise.
2. SLOW response is automatically selected when the peak current value is
detected to be changing periodically.
･ When measuring severe current fluctuations or low current levels in the
AUTO response mode, SLOW may be selected. In this case, select FAST or
SLOW manually as required.
･ It is not possible to change the response setting in the display hold or peak
hold mode (with the HOLD indicator lit or flashed, "Err.016" is displayed).
Press the
HOLD
key or
SHIFT
→
HOLD
keys to end the hold mode (so that the
HOLD indicator goes off), to make a change possible. However, with the
AUTO selection, the measurement is continued switching the response
setting, even if in the display hold mode.
