These indicators have marker needles indicating the maximum and minimum
values. The response time of these indicators is extremely fast.
The needle response time is 0.1s (0.3s for DC input).
The maximum value marker needle, minimum value marker needle and
driving needle are red, green and black, respectively.
Using the indicators in combination allows the marker needles to be reset to
the driving needle both manually and electromagnetically.

Note 1.
Models with a rating exceeding 15ADC are provided with an externally mounted 300mV shunt.
Additionally, in ordering, please specify the resistance value so that the lead wire round trip resistance value is 0.8Ω or less.
Remarks
(1) Refer to p.90 and p.92 if an AC voltmeter is to be used as a ground voltmeter.
(2) The T-150 rectifier is a dedicated accessory (non-compatible accessory) and thus cannot be used in
combinations besides those specified for the indicators. The distance between the indicator and the
T-150 rectifier must be 5m or less or the round trip lead wire resistance must be 0.5
Ω or less.
(3) Set the duration of supplying electricity to the electromagnetic marker needle resetting terminal to
within 5s. Additionally, use a switch that “opens” when released.
(4) The overload capacity is 2 times the rated current for 2s.
(5) For an AC ammeter or AC voltmeter, please specify the frequency.
(6) An expanded scale cannot be manufactured for an AC ammeter.
(7) Do not use with a circuit through which an inrush current or other current that exceeds the rating flows.
(8)
Please make sure to read the “Safety Precautions” (pp.5-8) and the “Selection Precautions” (p.9) to assist in selecting the model and use specifications suited to the application.
