ratio is 1:1 and it is input under other situations according to the transformation ratio of field TA);
Error:
the error parameters generated by the energy meter during field calibration. The
instrument can calculate the percentage of the values of electric quantity measured by the energy
meter and the difference in electric quantity actually measured by a standard meter according to
the input energy meter constant and collected energy meter power pulses).
Electrical parameter area:
The following kinds of all electrical parameters are shown:
U (V), I (A), φ(Angle), F (frequency), P (W), Q (Var), COSФ
U (field voltage value)
I (field current value) φ (phase shift angle) P (active value)
Q (reactive value) φ (power factor) F (frequency)
Input method identification
: "123" means Arabic numeral input, "ABC" refers to English
uppercase characters input, "ABC" means English lowercase characters input, and "Pin" is
Chinese character input.

. How to use the functions
3.1 Calibration information setting
Calibration parameter setting:
Photoelectric and manual mode
Photoelectric refers to using the light signals or pulse signals of the measured meter. The
"photoelectric" mode should be chosen by use of photoelectric sampler or when the pulse signal
of the measured meter is directly sent to the instrument’s photoelectric head interface.
Manual: means the "manual" should be chosen when using a manual switch for calibration.
Operation method: press "←, →" and the cursor jumps to the photoelectric and manual settings;
press [Confirm] key to lock the option.
For example: choose the photoelectric mode to measure the energy meter.
Press "←, →" keys to move the cursor to the photoelectric setting, and select the "photoelectric"
parameter value by pressing [Confirm] key.
Active and reactive power
Active (reactive): refers to the measurement of the energy meter’s active or reactive power
error.
Operation method: press "←, →" and the cursor jumps to the active and reactive power
setting, and press [Confirm] key to lock the option.
Such as: the active power error of the measured energy meter
Press"←, →" and move the cursor to the active power setting, and choose "active"
