The first unit, AAA, can be redefined by user for other special unit, see next section. Press the
confirm button (
) to select the unit. The selection is kept even power turned off.
CHB is for a transducer with output of 1 mV = 1 “unit”.
CHB always measures the input voltage with mV.
The “unit” is only a human readable indicator for the convenience of user, it does not change
the measurement.
The “unit” can be set as “mV” or “V” or “%RH” or “%” or “ohm” or “ABC”, and it only make
sense when it is set according to the output property of the transducer.
For example if we connect a humidity transducer with output 1 mV = 1 %RH to the CHB
(channel B) of the meter, the “unit” should be set as “%RH”. If user does not do so, then the
the unit becomes meaningless, but the measurement will not influenced.
8.10 CHB PARA-Create Special Unit for Channel B (CHB)
Changing each individual character of “AAA” to one of following can create special units.
(Characters available: upper case characters A to Z, lower case a to z, o, /, %,

, dot and blank
space).
Place rotary switch at position “CHB PARA”, This user defined unit (set as “AAA” when

acter can be changed with upward ( ) or downward ( ) direction buttons.
