socket should correspond to the power plug of the instrument.
（5）The instrument has been carefully designed for decreasing noise jamming caused by
the input in AC power terminal, but it is also recommended to use it in the
environment of low noise. If noises cannot be avoided, install a power filter please.
——————————————————————————————————
WARNING: To avoid injury to personnel and damage to the instrument resulting
from electric shock, do ensure that the earth ground wire is grounded.
1.4 Fuse
The fuse is a standard configuration, so use the included custom fuse please.
1.5 Environment
（1）Do not store or use the instrument where it could be exposed to many dusts, great
vibration, direct sunshine and corrosive gas.

relative humidity of no greater than 75%. For high accuracy, use the instrument in the
environment above mentioned.
（3）For high accuracy, do not block the left air vent so as to ensure good ventilation.
（4）The instrument has been carefully designed for decreasing noise jamming caused by
the AC power input, but it is also recommended to use it in the environment of low
noise. If noises cannot be avoided, install a power filter please.
（5）If the instrument will not be used for a long time, please place it in the original or a
similar packing box. The environment temperature should be kept in range of 5℃to
40℃, and the relative humidity should not be greater than 85%. The box should be
located in an airy room where it could not be exposed corrosive impurities and direct

Operation procedures are as follows:
Move to the RNG_R zone, the following items will be displayed:
AUTO Set the RNG_R asAUTO.
HOLD Switch the RNG_R from AUTO to HOLD. Since the RNG_R is set to
HOLD, the current measurement range will be locked and displayed in the
RANGE zone.
↑(+) Increase the range.
↓(-) Decrease the range.
Move to the RNG_V zone, the following items will be displayed:
AUTO Set the RNG_V as AUTO.
HOLD Switch the RNG_V from AUTO to HOLD. Since the RNG_V is set to
HOLD, the current measurement range will be locked and displayed in the
RANGE zone.
60V (TH2523)/300V (TH2523A) Select the displayed voltage range
6V(TH2523)/30V(TH2523A) Select the displayed voltage range
3.1.3 Measurement Speed
