RANG key to select resistance range or corresponding Graduation
of thermal resistance.
6. The Instrument will read the stable measured value. The refreshing rate for
measurement is nearly 1/second, and symbol'OL' may display on the screen if the
measured value is out of range.
Section Seven Setting Functions
Undertaking the following operation may change the auto-power-off
function or the temperature unit of the thermal resistance of the
Instrument.
1. Settings for auto-power-off function:
When the Instrument is on power-off state, press
〔
POWER
〕
key for full-screen
display, release
〔
POWER
〕
key and press
〔
RANG
〕
key immediately, the
Instrument will go into maintenance state, and symbol 'AP-XX'displaysonthescreen.
When pressing
〔
〕
key, the Instrument may remove auto-power-off function if
symbol 'AP- OF 'displays on the screen; The Instrument may
restore auto-power-off function if symbol 'AP- ON 'displays on the screen. Press
〔
4/3/2W
〕
key to store the setting.
1. When pressing
〔
〕
key, the Instrument will shift to the setting interface for
temperature unit of thermal resistance, and the symbol 'TC-OC'displays on the
screen, which means Celsius degree is the temperature unit;
2.When pressing
〔
〕
key, the Instrument will shift to the setting interface for
temperature unit of thermal resistance, and the symbol 'TC- OF 'displays on the
screen, which means

(“Counts” refers to the number of increments or decrements of the least
significant digit).
