Minolta XE - Confirmation of Minimum Working Voltage; Confirmation of B.C. Lamp Lighting Voltage

ao
Wi Confirmation of Minimum Working Voltage
& Measuring instruments:
: 081 standard circuit tester (Model SC-1) or constant-voltage DC power source (Model E-1 or E-2)
: Shutter tester
: Digital tester (Type 2507) or DC ammeter
: Power source adapter (081- 4204-79)
WStandard value Shutter speed | Standard value | Allowable value (+0.45Ev) |
| 1/1000 | 0.98 ms ___0.71~1.33ms
WiChecking procedures:
1. Set the measuring instruments as shown in the figure below, and set the power source voltage
at 1.70V. Release the shutter at a speed of 1/1000 and check that the measured value is within
the standard (0.71~1.33ms).

M@iMeasuring instruments:
: 081 standard circuit tester (Model SC-1) or constant-voltage DC power source (Model E-1 or E-2)
: Digital tester (Type 2507) or DC ammeter
: Power source adapter (081-4204-79)
WStandard value: J.ighting at over 1.71~2.0V
MiChecking procedures:
1. Set the measuring instruments as showin in the figure betow, and set the power source voltage
at 1.7V, turn down B.C. SW in the arrow direction and make sure that B.C. lamp is, “out”.
Next, set the power source voltage at 2.0V, turn down B,C. SW in the arrow. direction and see
if the B.C. lamp is lighted.
